#include<iostream>
#include<string>
#include<cmath>
using namespace std;
int main() {
    char a[40010]={'0'};
    int i=1,sum=0;
    while(cin>>a[i]) i++;
    cout<<sqrt(i);
    for(int j=1;j<i;j++) {
        if(a[j]==a[j-1]) sum++;
        else {
            cout<<sum<<" ";
            sum=1;
        }
    }
    cout<<sum;
    return 0;
}

这样还是输不出来

@tangjiayang Ctrl+Z是这样的

多了个^Z后换行

@DogSeven ?

不是按吗

by qczrz6v4nhp6u @ 2022-07-27 14:44:06

@tangjiayang 不i--的话长度会多一,sqrt(i)就不是整数

by qczrz6v4nhp6u @ 2022-07-27 14:46:34

@tangjiayang 雀食，按完^Z后要换行

by ttkuilei @ 2022-07-27 14:47:47

OK

能输出了

@DogSeven

可是我i--之后还是小数
