水题，注意初始化为-1，一开始初始化为0，坑了自己好几把。

代码如下：

#include<cstdio>
#include<cstring>
#include<iostream>
#include<algorithm>
using namespace std;
typedef long long ll;
const int N = 1e5+10;
int n, m, maxn, tmp;
ll a, cnt;
int sum[200];
int main()
{
	scanf("%d%d", &n, &m);
	memset(sum, 0, sizeof(sum));
	for(int i = 1; i <= m; i++)
	{
		cnt = -1;
		for(int j = 1; j <= n; j++)
		{
			scanf("%I64d", &a);
			if(cnt < a)
			{
				cnt = a;
				tmp = j;
			}
		}
		sum[tmp]++;	
	}
	maxn = -1, tmp = 0;
	for(int j = 1; j <= n; j++)
	{
		if(maxn < sum[j])
		{
			maxn = sum[j];
			tmp = j;
		}
	}
	printf("%d\n", tmp);
	return 0;
}
