Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int a, s[6], b;
  scanf("%d", &a);
  for (int i = 0; i <= 5; i++) s[i] = (a >> i) & 1;
  swap(s[0], s[4]);
  swap(s[2], s[3]);
  b = 0;
  for (int i = 0; i <= 5; i++) b += (s[i] << i);
  printf("%d\n", b);
  return 0;
