帮帮忙去掉就不会编译错误了

@small_bird strlen是n的，您的代码是 n^2的

by bird_秒切橙题 @ 2020-05-29 21:45:21

#include<bits/stdc++.h>
using namespace std;
char s[1001];
int n;
int main()
{
    cin>>n>>s;
    for(int i=0;i<=strlen(s)-1;i++)
    {
        int k=s[i]+n;
        while(k>'z')k-=26;
        cout<<char(k);
    }
}

@Zhaoyuhang2008 题水，n^4都OK

by HyyypRtf06 @ 2020-05-29 21:46:29

当然strlen写成这样也是很……

size是O(1)的

by bird_秒切橙题 @ 2020-05-29 21:47:05

没事反正都可以比赛的时候我才这样写
