Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
long long n, a[41];
int main() {
  a[0] = 1;
  for (int i = 1; i <= 12; i++) {
    a[i] = a[i - 1] * 2;
  }
  a[13] = 8092;
  for (int i = 14; i <= 35; i++) {
    a[i] = a[i - 1] * 2;
  }
  cin >> n;
  cout << a[n] << endl;
  return 0;
}
