A. Doggo Recoloring http://codeforces.com/contest/1025/problem/A 题目大意为将一个n长的字母串全部染成同一个颜色（字母）,但每次染色至少要有选择两个相同的字母。 可以染色任意次，问给定一个字符串，是否最后可以全部染成同一种颜色。 一开始错了1次因为题目意思都没看清，然后又因为没有考虑到只有一个字母的情况错了一次。 最后代码 #include <iostream> #include<bits/stdc++.h> using namespace std; const int MAXN=100000+10; char s[MAXN]; int n; int t[26]; int main() { cin>>n; cin>>s; for(int i=0;i<n;i++) t[s[i]-'a']++; sort(t,t+26); if(n!=1&&t[25]==1){ puts("No"); }else puts("Yes"); return 0; } 其实可以不用排序，也就是只统计是否出现过同种颜色（字母）两次以上，如果出现，则一定可以将所有字母染成同一种颜色（字母）， 另外注意只有一个字母的时候直接成立。 #include<bits/stdc++.h> using namespace std; int n,i,r,a[256

目录 一、正常模式 二、上下文格式（context diff） 三、合并格式的diff diff命令本身很简单，需要注意的是要会阅读其输出。 diff 的模式有三种 * 正常格式（normal diff） 　　* 上下文格式（context diff） 　　* 合并格式（unified diff） 一、正常模式 不带参数输出就是正常模式 11]# diff /dfs/acf/INDEX/202010/10/A1350AOIL05.TXT /dfs/acf/INDEX/202010/11/A1350AOIL05.TXT |more 1,101494c1,26841 < 002538 \A1575A1BPK1\A10A9\A10A902R\A10A902RCH\FORMAT\A1350A10A902RCH.TXT < 002538 \A1575A1BPK1\A10A9\A10A902R\A10A902RCH\GlassID\A1350A10A902RCH-Mark9.JPG < 002538 \A1575A1BPK1\A10A9\A10A902R\A10A902RCH\GlassID\A1350A10A902RCH-Mark10.JPG < 002538 \A1575A1BPK1\A10A9\A10A902R\A10A902RCH\GRAYIMAGE\A1350A10A902RCHDM

A : A. Doggo Recoloring time limit per test 1 second memory limit per test 256 megabytes input standard input output standard output Panic is rising in the committee for doggo standardization — the puppies of the new brood have been born multi-colored! In total there are 26 possible colors of puppies in the nature and they are denoted by letters from ' a' to ' z' inclusive. The committee rules strictly prohibit even the smallest diversity between doggos and hence all the puppies should be of the same color. Thus Slava, the committee employee, has been assigned the task to recolor some puppies
