明白了 只有两个ac是没有考虑到当第一个数就是1的情况 以下为改正后ac的代码：

#include<iostream>
#include<string>
using namespace std;
string strall;
int n,k = 0;
char t = '0';
int main() {
    cin >> strall;
    n = strall.length();
    for (int i = 1; i < n; i++) {
        string strtemp;
        cin >> strtemp;
        strall = strall + strtemp;
    }
    int num[100000] = {};
    for (int j = 0; j < n * n; j++) {
        if (strall[j] == t) {
            num[k]++;
        }
        else {
            num[k + 1]++;
            k++;
            if (t == '0')t = '1';
            else t = '0';
        }
    }
    cout << n<<" ";
    if (num[0] == 0) {
        cout << "0 ";
    }
    for (int j = 0; j < n*n; j++) {
        if (num[j] != 0) {
            cout << num[j]<<" ";
        }
    }
    return 0;
}

建议自删，讨论区别发标程（）
