寻找超大数字中的最大值

#include<bits/stdc++.h>  
using namespace std;

int main() {
    int n, c=1;
    cin >> n;
    string max, temp;
    cin >> max;
    for (int i = 2; i <= n; i++) {
        cin >> temp;
        if (max.size() < temp.size() || (max.size() == temp.size() && max < temp)) {
            c = i;
            max = temp;
        }
    }
    cout << c << endl << max;
    return 0;
