建议快读把break放到for的小括号里写，不然可能会炸

附上我的

#include<iostream>
#include<cstring>
using namespace std;
string a[205];
int x,y;
char c;
int main(){
    cin>>a[0];
    y=a[0].size();
    for(int i=1;i<y;i++)
        cin>>a[i];
    c=48;
    cout<<y<<" ";
    for(int i=0;i<y;i++)
        for(int j=0;j<y;j++)
        {
            if(a[i][j]==c)
                x++;
            else
            {
                cout<<x<<' ';
                x=1;
                if(c=='0')
                    c='1';
                else c='0';
            }
        }
    cout<<x<<endl;
    return 0;
}

@compatibility 可能这个数据行尾不是换行符

by compatibility @ 2023-09-22 23:33:27

@wrkwrkwrk 那是什么？

by compatibility @ 2023-09-22 23:33:47

@DiThgtrE_lsy 哪里的break？

by wrkwrkwrk @ 2023-09-23 10:20:08

@compatibility 你可以试一下freopen读入数据@compatibility，最后不打换行符

by compatibility @ 2023-09-23 16:55:46

@wrkwrkwrk 什么是freopen？抱歉，我只学了c..

by wrkwrkwrk @ 2023-09-23 17:03:24

@compatibility 或者你可以在你的输入最后按下ctrl+z

by compatibility @ 2023-09-23 23:30:01

@wrkwrkwrk 不用啊，我在VS上照示例输入结果是对的，但洛谷就不行了，不知道为什么

by wrkwrkwrk @ 2023-09-24 08:09:27

@compatibility 就是要ctrl+z才能出发（或者试试在终端运行？）
