我这个程序为什么测试的时候正确，但全WA

#include<iostream>

11行可能have点问题
if(b[i] != '0' && b[i] != 1)
例如例题，当输入完0001000后”换行“也属于！=’0‘ &&！=’1‘，导致只输入n个数后便停止
可以把整个换成
if(b[i] == '0' || b[i] == '1')n++；统计n

后面不太清楚，因为我bush这么做的其实是看不懂自己检查一下

#include <bits/stdc++.h>
using namespace std;
int main()
｛
string p;
cin>>p;
int c=p.size(),a[c*c],i,s,j;
bool f=0;
for(j=0;j<c;j++)
    a[j]=p[j]-'0';
for(i=1;i<c;i++)
{
    cin>>p; 
    for(j=i*c;j<i*c+c;j++)
        a[j]=p[j-i*c]-'0';
}
cout<<c<<" ";
i=0;
while(i<c*c)
{
    s=0;
    while(a[i]==f&&i<c*c)
    {
        s++;
        i++;
    }
    f=!f;
    cout<<s<<" ";
}
return 0;
}
有一个测试点是
0000000
0000000
0000000
0000000
0000000
0000000
我做的时候也卡了70

~~额~~
这样就AC

@guoyize 测试点太猥琐

@wangqicheng1637确实
