Sample input:
3 4
1 2 3 1
1 5 6 1

Sample output:
3

What is wrong,correct the error please

#include <iostream>
using namespace std;

int main() {
int n, m;
int max =0;
cin >> n >> m;
int aza[100][100];
for (int i = 1; i <= n; i++) {
for (int j = 1;j <= m; j++) {
cin >> aza[i][j];

}
}

for (int j = 1; j <= m; j++) {
int sum = 0;
for (int i = 1; i <= n; i++) {

sum+= aza[i][j];

}

}
int maxind = 0;
for (int j = 1; j <= m; j++) {
for (int i = 1; i <= n; i++) {

if (max < aza[i][j]) {
max = aza[i][j];
maxind = i;
}

}

}
cout << maxind;
