Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
long long int arr[40];
void init() {
  arr[0] = 1LL;
  for (int i = 1; i < 40; i++) {
    arr[i] = arr[i - 1] * 2LL;
    if (i == 13) arr[i] -= 100;
  }
}
int main() {
  init();
  int n;
  cin >> n;
  cout << arr[n] << endl;
}
