记录每组的最大值，并比较组间的最大值胖胖鼠~

#include<iostream>
using namespace std;
int main(){int n, m, ans, fat = -1, x;scanf("%d%d", &n, &m);for(int i = 0; i < n; i++){ans = -1;for(int j = 0; j < m; j++){scanf("%d", &x);if(x > ans) ans = x;}if(ans > fat) fat = ans;if(i) printf(" ");printf("%d", ans);}printf("\n%d", fat);return 0;
}
