挑战赛的题 为什么用float只得了40分，double就AC了😂

试卷怎么关闭呀？

有人知道为什么acgo在学校的电脑里不能写代码吗？

ACGO在一些设备交不了代码，比如我们学校电脑，可以登录，可以看题，可以发帖，但是交不了代码，交代码的地方都是一片空白，有人知道为啥吗 如图： ACGO又得忙了

#include <bits/stdc++.h> using namespace std; int main(){ string str; cin>>str; for(int i=0;i<=str.size();i++){ int x=0; x=(int)str[i]; if(x>=65&&x<=87||x>=97&&x<=119){ x=x+3; str[i]=(char)x; }else{ x=x-23; str[i]=(char)x; } } for(int i=str.size()-1;i>=0;i--){ cout<<str[i]; } }
