so "difficult"

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

    string name;
    int weight;

int main(){
    int n;
    cin >> n;
    for(int i = 1; i <= n; i++){
        cin >> a[i].name >> a[i].weight;
    }
    for(int i = 1; i <= n; i++){
        cout << a[i].name << "->" << a[i].weight << "\n";
    }
    return 0;
}
