Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int solve(int n) {
  vector<int> a;
  while (n != 0) {
    a.push_back(n % 2);
    n /= 2;
  }
  while (a.size() < 6) {
    a.push_back(0);
  }
  reverse(a.begin(), a.end());
  swap(a[1], a[5]);
  swap(a[2], a[3]);
  int ans = 0;
  reverse(a.begin(), a.end());
  for (int i = 0; i < a.size(); i++) {
    ans += pow(2, i) * a[i];
  }
  return ans;
}
int main() {
  ios_base::sync_with_stdio(false);
  cin.tie(NULL);
  cout.tie(NULL);
  int n;
  cin >> n;
  cout << solve(n);
}
