No need to figure out product line up – just get amCharts 5 for everything. And since it was designed to work with modern web dev toolkits like React, Angular, Vue it will just fall into place, right out of the box. X/Y Line & Smoothed line Area Column & Bar Scatter & Bubble Candlestick & OHLC Step (incl. w/ no-riser) Floating & Gantt Waterfall Error Stacked (regular or 100%) Heatmap … and any combination of the above Percent Pie & Donut Nested donut Funnel Pyramid Pictorial Geo maps Map chart Geo heat map Map combined with charts Maps is an add-on and requires separate license. Other Sankey diagram Chord, Chord directed, and Chord non-ribbon diagrams Pack Treemap Tree Sunburst Partition Force-directed tree Radar & Polar Word cloud Venn diagram Efficiency built-in Canvas rendering amCharts 5 uses browser’s Canvas API which in most cases is way faster than SVG. Less moving parts in the DOM tree, faster rendering. Layering Common element groups are isolated into separate independent canvases, so that heavily updated sections do not trigger expensive repaints in places that do not change. Fast data processing Data processing in amCharts 5 is designed to be as efficient as possible. Incremental updates, lack of repetitive aggregations, and lightweight data object use makes data processing fast and very memory-efficient. Faster dashboards amCharts 5 is capable of running scores of charts on the same page, without crippling the browser, due to its lightweight approach to data parsing and rendering. Tiny binaries We made amCharts 5 really small – the core functionality compiles to a file of only around 400KB. Each niche functionality is separated into files, so you load only what you really need. Users will surely appreciate faster load times. Better tree-shaking We also designed amCharts 5 to be extremely tree-shakable. If you are using Webpack or similar packager, only code that is really needed will be included into your final application. The most advanced chart package Classics with some new twists XY charts are now so powerful and flexible, you can plot any data on them. Number, date, duration, or category axes are supported, in all directions. Pie charts are now fully nestable, with support for custom start and end angles, to create half circles. New geo maps Our maps use GeoJSON format. Being open and widely accepted standard it opens up a lot of possibilities and sources for ready-made and custom maps. Furthermore, maps are now very flexible, with multi-series support, configurable down to the nut and bolt. (Maps is and add-on to amCharts 5: Charts which requires separate license) More about amCharts 5: Maps Pictorials Create multi-layer, multi-series pictorial charts. Any SVG path can be used as a shape for your chart. Sankey Diagrams Stunning flow diagrams, in horizontal and vertical. With draggable, fully configurable nodes. Enhanced radar charts With stacked column, bands, axes, and other dramatic enhancements, radar charts are now way more useful. Treemaps Completely zoomable, multi-level, highly configurable. Heatmaps Automatically build heat-maps, with custom axes, color ranges, and awesome new interactive Heat Legend. Create heatmaps using colors, or point size or both. Universal and flexible heat rules allow attaching any value in data to any property or properties on any element. Chord diagrams Visualize your 2-way relational data in a neat circular Chord diagrams. We do have different variations of the classic diagram: Chord, Chord directed, and Chord non-ribbon. True funnel charts amCharts 5 offers true Funnel charts the way they were meant to be. Slice’s area size represents the value, so each step’s influence on overall volume reduction is more prominent than with basic funnels. Trapezoid form can also be configured to further emphasize reduction. Complete it with other visual elements, like fully configurable slice lines, multiple series support, togglable legends, and many many more options. Customizable beauty built-in Powerful theme engine amCharts 5 comes with a bunch of beautiful themes as well as a super flexible theme engine, which you can use. We devised a CSS-like rule-based theme targeting system in themes. Using, creating, customizing themes or standalone rules has never been so easy. The new system allows applying defaults to elements based on their type, features, or position in a virtual element tree. Fresh new look Default looks designed to look fresh, like something out of tomorrow. Carefully selected color schemes and default settings were specifically chosen to make the charts stand out. Silk-smooth animations Every setting – colors, positions, sizes, opacity, and many more – is animatable to ensure smooth transitions. No choppy, stepped animations – everything is fluid, including zoom and toggling of series and other items. Flexibility Element templates Most elements are created using templates: a collection of default settings, events, and adapters. Changing template automatically propagates changes to actual elements, making it easy to do batch updates. Everything’s configurable Numerous configuration options allow inventive uses, bordering on new chart types. Angles, colors, positions, radii, a-n-y-t-h-i-n-g can be set to bend classic and new chart types exactly the way you need them. Element states Easily change how an element looks like under different circumstances, e.g. on some interaction, hover, click, or related to data (eg. column look if a value is down). The engine will automatically apply the required properties as needed, animating between old and new values smoothly. Create and apply custom states via the API. Multi-type multi-axis support Add any number of axes of any type. Create overlaid comparison of different time scales. Use any mix of dimensional values: numbers, dates, categories, or duration. Adapters “Adapters” functionality allows plugging in custom code to dynamically override just about any setting or data value. Text formatting All text labels – tooltips, axis labels, titles, etc. – now support rich text formatting options, like changing colors, font weight, or applying just about any styling option from the CSS arsenal. In addition to formatting support, labels can now contain in-line placeholders for real data, with the ability to apply custom formatting to values. Accessibility & Interactivity Accessibility Accessibility was riding shotgun when amCharts 5 was being developed. All interactive elements are TAB-selectable, with customizable roles, order, and screen-reader texts. Everything that can be moved by touch or mouse, can be moved by keyboard. Everything that can be clicked or toggled, can be interacted with with keyboard, too. Touch support Charts have been designed to work with touch devices out-of-the-box. They will work not only on phones or tablets, but also touch capable computers. Under the hood Built with TypeScript Supports strong type and error checking in TypeScript applications. Enjoy code completion, error checking and dynamic help popups in major IDEs. Full support for TypeScript and ES6 modules. 100% for JavaScript Can be fully used in any vanilla JavaScript application. amCharts 5 does not use or rely on globals, external frameworks or 3rd party libraries. Universal rendering engine Can be used to build dynamic, interactive Canvas-based interfaces and applications. Add various elements to the screen, make them interactive, with a few lines of code. Make them clickable, draggable, hoverable, using built-in interactivity functionality. Our universal layout engine will place, size and arrange elements according to set rules. 本篇文章为转载内容。原文链接：https://blog.csdn.net/john_dwh/article/details/127460821。 该文由互联网用户投稿提供，文中观点代表作者本人意见，并不代表本站的立场。 作为信息平台，本站仅提供文章转载服务，并不拥有其所有权，也不对文章内容的真实性、准确性和合法性承担责任。 如发现本文存在侵权、违法、违规或事实不符的情况，请及时联系我们，我们将第一时间进行核实并删除相应内容。

For example, the strings “z”, “aaa”, “aba”, and “abccba” are palindromes, but “codeforces” and “ab” are not. You hate palindromes because they give you déjà vu. There is a string s . You must insert exactly one character ‘a’ somewhere in s . If it is possible to create a string that is not a palindrome, you should find one example. Otherwise, you should report that it is impossible. For example, suppose s= “cbabc”. By inserting an ‘a’, you can create “acbabc”, “cababc”, “cbaabc”, “cbabac”, or “cbabca”. However “cbaabc” is a palindrome, so you must output one of the other options. Input The first line contains a single integer t (1≤t≤104 ) — the number of test cases. The only line of each test case contains a string s consisting of lowercase English letters. The total length of all strings does not exceed 3⋅105 . Output For each test case, if there is no solution, output “NO”. Otherwise, output “YES” followed by your constructed string of length |s|+1 on the next line. If there are multiple solutions, you may print any. You can print each letter of “YES” and “NO” in any case (upper or lower). Example Input Copy 6 cbabc ab zza ba a nutforajaroftuna Output Copy YES cbabac YES aab YES zaza YES baa NO YES nutforajarofatuna Note The first test case is described in the statement. In the second test case, we can make either “aab” or “aba”. But “aba” is a palindrome, so “aab” is the only correct answer. In the third test case, “zaza” and “zzaa” are correct answers, but not “azza”. In the fourth test case, “baa” is the only correct answer. In the fifth test case, we can only make “aa”, which is a palindrome. So the answer is “NO”. In the sixth test case, “anutforajaroftuna” is a palindrome, but inserting ‘a’ elsewhere is valid. 题意： 给你一个字符串，然后你可以通过在任意位置上+‘a’，然后让这个字符串不是回文字符串，如果实在无法让字符串变成非回文，则输出NO。 思路： 我们可以判断出只有全为a的回文字符串才会+‘a’后无法变成非回文串，其他的都可以在任意位置上“a”，使字符串变成非回文串，那我们可以直接在首或者尾“a”，然后循环判断是否为回文，输出非回文的那一种就可以了。 代码： include<bits/stdc++.h>using namespace std;bool judge(string p){for(int i=0,j=p.size()-1;i<j;i++,j--){if(p[i]!=p[j])return true;}return false;}int main (){int t;cin>>t;while(t--){string ch;cin>>ch;int f=0;for(int i=0;i<ch.size();i++){if(ch[i]!='a'){f=1;break;} }if(f==0){cout<<"NO"<<endl;}else{string ch1,ch2;ch1="a"+ch;ch2=ch+"a";if(judge(ch1)){cout<<"YES"<<endl;cout<<'a';for(int i=0;i<ch.size();i++) cout<<ch[i];cout<<endl;}else{if(judge(ch2)) {cout<<"YES"<<endl;for(int i=0;i<ch.size();i++) cout<<ch[i];cout<<'a';cout<<endl;}elsecout<<"NO"<<endl;} }}return 0;} B. Flip the Bits time limit per test 1 second memory limit per test 256 megabytes input standard input output standard output There is a binary string a of length n. In one operation, you can select any prefix of a with an equal number of 0 and 1 symbols. Then all symbols in the prefix are inverted: each 0 becomes 1 and each 1 becomes 0 For example, suppose a=0111010000 since it has four 0’s and four 1’s: [01110100]00→[10001011]00 In the second operation, we can select the prefix of length 2 since it has one 0 and one 1: [10]00101100→[01]00101100 It is illegal to select the prefix of length 4 for the third operation, because it has three 0’s and one Can you transform the string a into the string b using some finite number of operations (possibly, none)? Input The first line contains a single integer t (1≤t≤104) — the number of test cases. The first line of each test case contains a single integer n (1≤n≤3⋅105) — the length of the strings a and b The following two lines contain strings a and b of length n, consisting of symbols 0 and 1 The sum of n across all test cases does not exceed 3⋅105 Output For each test case, output “YES” if it is possible to transform ainto b, or “NO” if it is impossible. You can print each letter in any case (upper or lower). Example Input Copy 5 10 0111010000 0100101100 4 0000 0000 3 001 000 12 010101010101 100110011010 6 000111 110100 Output Copy YES YES NO YES NO Note The first test case is shown in the statement. In the second test case, we transform a into b by using zero operations. In the third test case, there is no legal operation, so it is impossible to transform a into b . In the fourth test case, here is one such transformation: Select the length 2 prefix to get 100101010101 . Select the length 12 prefix to get 011010101010 . Select the length 8 prefix to get 100101011010 . Select the length 4 prefix to get 011001011010 . Select the length 6 prefix to get 100110011010 In the fifth test case, the only legal operation is to transform a into 111000. From there, the only legal operation is to return to the string we started with, so we cannot transform a into b 题意： 给你一个字符串a，b，由0,1组成，然后只有在字符串下标i前面的0,1个数相同时，你可以进行把0->1,1->0,然后看是否能进行一些操作把字符串a变成b。 思路： 这题思路有点难想，你看，它每次个数相同时，都可以进行操作，所以我们从后往前进行操作，因为如果从前往后，小区间会影响大区间的，所以从大区间向小区间进行，然后遍历字符串，将每一位的0,1的个数进行计算，然后将a，b不相同的下标进行标记为1，代表需要改变。 从后遍历，cnt进行次数，因为如果是奇数的话，才会变成不一样的数字，偶数的话，区间变化会使它变回去了，在判断当前位之前，我们先看之前的大区间的变化将当前第i位变成了什么，因为只有0,1，跟标记的0,1是代表他是否需要变化，假如说：原先为0，他后面的区间将它变化了奇数次，那么它就现在是需要变化的才能变成吧b。原先为1，它后面的区间将它变化了偶数次，就还是1。如果这个下标的标记为1，代表需要被变化，我们就判断当前位的0,1个数是否相同，相同的话就代表了一次变化cnt++，否则就退出无法变成b了，因为之后没有区间将它再次变化了。然后我们就可以判断了 代码： include<bits/stdc++.h>using namespace std;const int N=3e5+7;int s0[N],s1[N];int a[N],b[N],p[N];int main (){int t;cin>>t;while(t--){int n;cin>>n;string a,b;cin>>a>>b;memset(p,0,sizeof p);for(int i=0;i<n;i++){if(a[i]=='0'){s0[i]=s0[i-1]+1;s1[i]=s1[i-1];}else{s1[i]=s1[i-1]+1;s0[i]=s0[i-1];}if(a[i]!=b[i]){p[i]=1;//是否相同的标记} }int cnt=0;int f=0;for(int i=n-1;i>=0;i--){if(cnt%2==1){//奇数次才会被变化p[i]=1-p[i];}//而且必须在前面判这一步，因为你得先看后面的区间将这一位变成了什么if(p[i]){if(s0[i]==s1[i]) cnt++;//0,1相同时才可以进行一次变化else {f=1;break;} }}if(f==1){cout<<"NO"<<endl;}else{cout<<"YES"<<endl;} }return 0;}//这个就利用了一个标记来判断当前为被影响成了什么/01 01 01 01 01 0110 01 10 01 10 10100101010101011010101010100101011010011001011010100110011010Select the length 12prefix to get.Select the length 8prefix to get.Select the length 4prefix to get.Select the length 6prefix to get01 110100 0001 001011 00/ C. Balance the Bits time limit per test 1 second memory limit per test 256 megabytes input standard input output standard output A sequence of brackets is called balanced if one can turn it into a valid math expression by adding characters ‘+’ and ‘1’. For example, sequences ‘(())()’, ‘()’, and ‘(()(()))’ are balanced, while ‘)(’, ‘(()’, and ‘(()))(’ are not. You are given a binary string s of length n. Construct two balanced bracket sequences a and b of length n such that for all 1≤i≤n if si=1, then ai=bi if si=0, then ai≠bi If it is impossible, you should report about it. Input The first line contains a single integer t (1≤t≤104) — the number of test cases. The first line of each test case contains a single integer n (2≤n≤2⋅105, nis even). The next line contains a string sof length n, consisting of characters 0 and 1.The sum of nacross all test cases does not exceed 2⋅105. Output If such two balanced bracked sequences exist, output “YES” on the first line, otherwise output “NO”. You can print each letter in any case (upper or lower). If the answer is “YES”, output the balanced bracket sequences a and b satisfying the conditions on the next two lines.If there are multiple solutions, you may print any. Example Input Copy 3 6 101101 10 1001101101 4 1100 Output Copy YES ()()() ((())) YES ()()((())) (())()()() NO Note In the first test case, a= “()()()” and b="((()))". The characters are equal in positions 1, 3, 4, and 6, which are the exact same positions where si=1 .In the second test case, a= “()()((()))” and b="(())()()()". The characters are equal in positions 1, 4, 5, 7, 8, 10, which are the exact same positions where si=1 In the third test case, there is no solution. 题意： 一个n代表01串的长度，构造两个长度为n的括号序列，给你一个01串，代表着a，b两个序列串字符不相同。然后你来判断是否有合理的a，b串。有的话输出。 思路： 这题想了很久想不明白，看了大佬的题解，迷迷糊糊差不多理解吧。这题是这样的，就是： （1）第一步得合法的字符串，所以首尾得是相同的且都为1 （2）第二步，因为01串长度为偶数，所以如果合法的话，得（ 的个数= ) 的个数，然后你想呀，假如为 ()()()()吧，然后你有一个0破坏了一个括号，但如果合法的话，是不是得还有一个0再破坏一个括号，然后被破坏的这俩个进行分配才能合理，所以如果合法的话，01串得0的个数为偶数，1的个数自然而然为偶数吧。 （3）最后一步构造，既然1的个数为偶数，首尾又都为1，所以1的个数前sum1/2个1构造为‘（ ’，后sum1/2个构造为‘）’，然后我们1的所有的目前是合法的，然后剩下的0也是偶数的，然后如果让他们合法进行分配就（ ）间接进行就可以了，然后我们根据01串将b构造出来。合法的核心就是当前位的（个数大于等于），所以我们在循环进行判断一下a，b串是否都满足，（其实我觉得这么构造出来，a必然合理呀，其实就判b就行了，我保险起见都判了）。 代码： include<bits/stdc++.h>using namespace std;const int N=3e5+7;char a[N],b[N];int main (){int t;cin>>t;while(t--){int n;cin>>n;string s;cin>>s;if(s[0]!=s[n-1]&&s[0]!='1'){cout<<"NO"<<endl;}else{int sum1=0,sum0=0;for(int i=0;i<s.size();i++){if(s[i]=='1') sum1++;else sum0++;}if(sum1%2!=0||sum0%2!=0){cout<<"NO"<<endl;}else{int cnt1=0,cnt0=1;for(int i=0;i<n;i++){if(s[i]=='1'&&cnt1<sum1/2){a[i]='(';cnt1++;}else if(s[i]=='1'&&cnt1>=sum1/2){a[i]=')';cnt1++;}else if(s[i]=='0'&&cnt0%2==1){a[i]='(';cnt0++;}else if(s[i]=='0'&&cnt0%2==0){a[i]=')';cnt0++;}//cout<<a[i]<<endl;}for(int i=0;i<n;i++){if(s[i]=='0'){if(a[i]=='(') b[i]=')';else b[i]='(';}else{b[i]=a[i];}//cout<<b[i]<<endl;}// cout<<"YES"<<endl;int f=0;int s0=0,s1=0;for(int i=0;i<n;i++){if(a[i]=='(') s0++;else if(a[i]==')') s1++;if(s0<s1) {f=1;break;} }s0=0,s1=0;for(int i=0;i<n;i++){if(b[i]=='(') s0++;else if(b[i]==')') s1++;if(s0<s1) {f=1;break;} }if(f==0){cout<<"YES"<<endl;for(int i=0;i<n;i++) cout<<a[i];cout<<endl;for(int i=0;i<n;i++) cout<<b[i];cout<<endl;}else{cout<<"NO"<<endl;} }} }return 0;}/01 01 01 01 01 0110 01 10 01 10 10100101010101011010101010100101011010011001011010100110011010Select the length 12prefix to get.Select the length 8prefix to get.Select the length 4prefix to get.Select the length 6prefix to get01 110100 0001 001011 00/ 本篇文章为转载内容。原文链接：https://blog.csdn.net/lvy_yu_ET/article/details/115575091。 该文由互联网用户投稿提供，文中观点代表作者本人意见，并不代表本站的立场。 作为信息平台，本站仅提供文章转载服务，并不拥有其所有权，也不对文章内容的真实性、准确性和合法性承担责任。 如发现本文存在侵权、违法、违规或事实不符的情况，请及时联系我们，我们将第一时间进行核实并删除相应内容。

NLP? 数据库？分布式系统？其他？ 硕士？直博？ 小老师？大牛老师？ 以上这些选择因人而异，最好自己多了解、多与老师学长学姐交流，根据自己的兴趣、目前的发展以及自己未来的规划进行抉择。 夏令营(4-7月)：从四月份开始就有的学校开始了夏令营申请，5-6月是夏令营申请的集中时间；参加夏令营基本都在6-7月份。夏令营的好处：老师名额多；时间比较充裕，可以较好的了解学校以及方向等；大多学校夏令营安排住宿。参加夏令营最重要的是专业排名(这是大多数学校初筛的最重要的依据，科研经历/比赛等都是次要的。当然顶会和ACM大牛除外)。 预推免(7-9月)：有的学校夏令营开始后马上就开始预推免的报名与进行(例如哈工大从7月份开始到9月份有四批预推免的面试)；大多数学校集中在9月中旬。如果夏令营已经有offer了可以在预推免时冲击更好的offer；如果夏令营没有拿到offer，建议此时以稳重为好。 九推：9月28号在推免系统正式填报推免志愿，录取。 个人简历：建议在寒假期间就把自己大学的经历都整理一遍，写好简历的初始版本；然后再找老师、学长学姐帮忙完善。 个人陈述：包括自己的情况介绍、科研经历、研究生期间的规划等，1000-1500字。网上有模板可以借鉴。 老师推荐信：基本都是自己写好找老师签字，如果老师能帮你手写的话，那太好不过了。 联系老师邮件：建议提前写好一个大概的模板，注意格式、内容以及邮件的标题等(例如XX大学-XXX-保研申请)。建议夏令营前或者初审过了及时联系自己喜欢的老师。 以上只是对各方面的简单介绍，每个方面详细的注意点网上好多资料，多多搜集就好。 PS：以上个人简历/个人陈述/老师推荐信模板如果有需要的私信我分享给你！ 建议把以上材料都提前收集整理好，保研结束后发现我的材料文件夹3个多G...... 一年多来整理的保研资料 四、上科大信息学院夏令营(7.3-7.6) 本来没有打算报名上科大，一个同学把上科大宣传单给了我一份，看后感觉上科大实力比较强(虽然不是982/211)就报名了。 校园环境 上科大3号报到，4号-6号有开营活动、参观、自己联系老师面试(后来才知道即使拿到优营九月份也要再来面试，也就是说上科大夏令营拿到优营只是免去了九月预推免面试的初审，但是如果你足够优秀，老师比较中意，九月份就是来走一下过场。) 我参加了三个老师的面试。YY老师只是简单问了几个问题，有点水；HXM老师有一轮笔试(考的概率论比较多，编译原理、操作系统、计网也有涉及)+面试；YJY老师的一轮面试是课题组的学长学姐面的(自我介绍+项目)，二轮面试和老师聊。 上科大给我的感觉就是学校小而精；老师比较好(比如YJY/GSH/TKW)、科研氛围浓厚、硬件设施完善(双人宿舍，独立卫浴，中央空调；学校地下全是停车场，下雨不用打伞可以直接走地下)，但是由于建立才几年的时间，知名度不高。 学生宿舍 五、北理计算机夏令营(7.8-7.10) 北理今年入营的基本都是985和顶尖211，夏令营去了基本都能拿到优营！入营290+，夏令营参营240+，优营220+。 在北理主楼俯瞰 8号报到，领取宿舍钥匙、校园卡(北理夏令营包括食宿，每人发了一张100元的校园卡，可以在食堂、超市消费)。北理校园比较小、路比较窄；研究生宿舍三栋高层，有电梯，四人间，宿舍空间小、比较挤，大多数宿舍有空调(据说是宿舍的同学自己买或者租的)，每一层有一个公共洗澡间。 9号上午宣讲，下午机试。机试两道题目难度不大，老师手动输入三个样例给分(4+3+3，每道题目满分10分)。下午机试结束我找到提前联系的LX老师聊了一个小时，老师人很nice，专心学术(据说她的研究生大都有一篇顶会论文)。 10号上午自己找老师面试。我又参加了院长实验室的面试，比较简单。下午正式面试，分了十多个组一起面试，总共四个小时。面试包括英文自我介绍、项目、研究生规划、是否打算读博、基础知识等，每人大概5-7分钟。面试结束就可以离校了。 六、北航计算机夏令营(7.11-7.14) 北航是不包含食宿的，所以入营人数较多，有600+。北航7.11上午报到+宣讲，下午机试分两组。北航机试类似CSP，可以多次提交，以最后一次为准，但是提交后不能实时出成绩。机试两个小时，包括两道题目，第一道题目比较简单，第二道题目稍微难一些，我第二道题目没有写完但是也过了机试，第二道题目即使没有写完也要能写多少写多少，把代码的思路写出来(有可能会人工判)。北航机试可以用CSP成绩代替，基本250分及以上就没问题，每年具体的情况不一样。11号晚上出机试通过名单(大概500+进340+)。 12号分组面试，每人20分钟，从上午八点一直面试到下午三点。面试包括抽取一道政治题谈看法、抽取一段英文读并翻译、基础知识(数学知识+计算机知识)、项目。政治题和英文翻译感觉大家都差不多(除非你英语特别差)，主要的是基础知识面试，北航比较爱问数学问题线代、概率论、离散、高数；如果你的项目比较好的话，老师会着重问你的项目。问到我的问题有梯度、可微和可导、大数定理+中心极限定理等。12号晚上出优营名单，大概340+进180。北航是根据夏令营面试排名来定学硕和专硕的，大概有40个学硕的名额，其他都是专硕，不过北航学硕和专硕培养方式没有区别。 这是在我前面面试同学被问到的部分问题 13号领导师意向表，找导师签字，如果没有找到暑假期间或者九月份也可以再联系老师。 14号校医院体检，夏令营结束。 七、计算所(7.13-7.16) 计算所入营还是比较有难度的，但是即使没入营也可以自己联系老师，如果老师同意可以来参加面试，只是夏令营包括食宿，没入营的不包括食宿。计算所是分实验室面试的，可以参加多个实验室的面试，我参加了网数和智信的笔试+机试+面试。 智信12号笔试，14号机试+面试。笔试包括英文论文理解翻译、概率论题、计算机基础知识题目(操作系统，计网等)、CV题目(智信主要是做CV)。机试五道题目，一个小时，题目代码已经写好了，只需你补全，类似LeetCode，在学长的电脑上完成，有C++和Python可选，两种编程语言题目不同。C++用的是VS2017，会由人给你记每道题目完成的时间，会让你演示调试，结束后打包发送到一个邮箱里。 网数只有机试和面试,13号上午机试，15号面试。机试一个小时七道题目，在自己电脑上写然后拷到老师的优盘上。考察了包括链表、二叉树、图等，偏向于工程，据说今年的题目是计算所一个工程博士出的。机试70人，进入面试60人。面试每人15分钟，包括自我介绍，专业知识，是否读博，项目等。 计算所环境 八、一些建议和感想 一些建议： 提前准备，给自己定位，有针对性的准备，多在网上找经验贴；多和本校保研的学长学姐交流，多和同学交流，多搜集信息； 4月份前把简历、推荐信、个人陈述等写好，再不断修改完善； 最好能提前联系一个老师，以免拿到优营而没有找到好老师； 准备好专业知识，线代、概率论、数据结构、计网、计组、操作系统等； 如果编程能力不是特别强，最好大三开始就刷题，LeetCode的中档题难度基本就够用了； 一些体会与感想： 机会是留给有准备的人的，越努力越幸运！ 做最坏的打算，做最好的准备。 保研是一场马拉松，坚持到底就是胜利。 遵道而行，但到半途需努力；会心不远，欲登绝顶莫辞劳。 也送给自己一句话：流年笑掷，未来可期！ 以上仅代表个人观点与感想，如果对你有帮助记得点赞哦~如有问题，可以关注我的公主号【驭风者小窝】，我会尽我最大的努力帮助你！ 本篇文章为转载内容。原文链接：https://blog.csdn.net/weixin_28983299/article/details/118319985。 该文由互联网用户投稿提供，文中观点代表作者本人意见，并不代表本站的立场。 作为信息平台，本站仅提供文章转载服务，并不拥有其所有权，也不对文章内容的真实性、准确性和合法性承担责任。 如发现本文存在侵权、违法、违规或事实不符的情况，请及时联系我们，我们将第一时间进行核实并删除相应内容。
