Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int n;
  cin >> n;
  int temp;
  int a[6] = {0};
  int i = 0;
  while (n > 0) {
    a[i] = n % 2;
    n = n / 2;
    i++;
  }
  temp = a[0];
  a[0] = a[4];
  a[4] = temp;
  temp = a[2];
  a[2] = a[3];
  a[3] = temp;
  int count = 1;
  int sum = 0;
  for (int i = 0; i < 6; i++) {
    sum = sum + a[i] * count;
    count = count * 2;
  }
  cout << sum;
}
