以前ACM在哈工程HRBEU做的一些简单题目

#include <iostream>
using namespace std;
int main()
{
	int p[100][100];
	int n,i,j,sumr,sumc,r,c,sr,sc;
	while(cin>>n)
    {
		if(n==0)break;
		for(i=0;i<n;i++)
			for(j=0;j<n;j++)
				cin>>p[i][j];
			r=c=2;
		for(i=0;i<n;i++)
		{
			sumr=sumc=0;
			for(j=0;j<n;j++)
			{
				sumr+=p[i][j];
				sumc+=p[j][i];
			}
			if(sumr%2!=0){sr=i;r--;}
			if(sumc%2!=0){sc=i;c--;}
		}
		if(r<=0||c<=0)cout<<"Corrupt"<<endl;
		else if(r==2&&c==2)cout<<"OK"<<endl;
		else cout<<"Change bit ("<<sr+1<<","<<sc+1<<")"<<endl;
	}
	return 0;
}
