明明是对的啊为什么判错？ 有人帮我看看吗

#include<bits/stdc++.h>
using namespace std;
int main()
{
	string str; cin >> str;
	int N = str.size();
	vector<string>v(N);
	v[0] = str;
	for (int i = 1; i <= N - 1; i++)cin >> v[i];
	cout << N<<" ";
	int num = 0;
	char p = (v[0])[0];
	for (int i = 0; i < N; i++)
	{
		for (int j = 0; j < N; j++)
		{
			if (p == (v[i])[j])num++;
			else
			{
				cout << num<<" ";
				num = 1;
				p = (v[i])[j];
			}
		}
	}
	cout << num<<" ";
	return 0;
}
