太简单了

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

int n , a[200] , x , t , j; 

int main(){
	cin >> n , n = pow(2 , n);
	for(int i = 1 ; i <= n ; i++){cin >> a[i]; if(a[i] > x) x = a[i] , t = i;}
	if(t <= n / 2) x = n / 2 + 1;
	else x = 1 , n /= 2; t = 0;
	for(int i = x ; i <= n ; i++) if(a[i] > t) t = a[i] , j = i;
	cout << j;
	return 0;
