两个AC点，三四五错了

#include <iostream>

using namespace std;

bool cmp(int x,int y){
    return x > y;
}

long long piao[1000000] = {};
long long biao[1000000] = {};

int main(){
    int n;
    cin >> n;
   
    
    for(int i = 1;i <= n;i++){
        cin >> piao[i];
    }
    
    long long max = 0;
    for(int i = 0;i < n;i++){
        if(piao[i] > max){
            max = piao[i];
        }
    }
    
    for(int i = 1;i <= n;i++){
        if(piao[i] == max){
            cout << i << endl;
            cout << piao[i];
        }
    }

	return 0;
}
