Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int di[] = {0, 1, 1};
int dj[] = {1, 0, 1};
int dx[] = {0, 0, 1, -1, 1, 1, -1, -1};
int dy[] = {1, -1, 0, 0, 1, -1, 1, -1};
const int N = 55;
int main() {
  ios::sync_with_stdio(false), cin.tie(NULL), cout.tie(NULL);
  int x;
  cin >> x;
  string s;
  while (x) s += (x & 1) + '0', x >>= 1;
  while ((int)(s).size() < 6) s += '0';
  reverse((s).begin(), s.end()), swap(s[1], s[5]), swap(s[2], s[3]);
  for (int i = 0; i < 6; ++i) x <<= 1, x |= (s[i] - '0');
  cout << x << '\n';
  return 0;
