Solution:
#include <bits/stdc++.h>
using namespace std;
char s[100];
int main() {
  int x;
  int trans[] = {4, 1, 3, 2, 0, 5};
  int t[6];
  int y = 0;
  scanf("%d", &x);
  for (int i = 0; i < 6; i++) t[trans[i]] = i;
  for (int i = 0; i < 6; i++) {
    if (x >> (i)&1) {
      y |= (1 << trans[i]);
    }
  }
  printf("%d\n", y);
  return 0;
