Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int mapx[6] = {32, 1, 4, 8, 2, 16};
int main() {
  ios_base::sync_with_stdio(false);
  cin.tie(0);
  cout.tie(0);
  int result = 0;
  int k;
  cin >> k;
  for (int i = 0; i < 6; i++)
    if (k & (1 << i)) result += mapx[5 - i];
  cout << result;
  return 0;
