Solution (in PYTHON):

Solution:
import atexit
import io
import sys
import math
from collections import defaultdict

_INPUT_LINES = sys.stdin.read().splitlines()
raw_input = iter(_INPUT_LINES).next
_OUTPUT_BUFFER = io.BytesIO()
sys.stdout = _OUTPUT_BUFFER

@atexit.register
def write():
    sys.__stdout__.write(_OUTPUT_BUFFER.getvalue())

t=int(raw_input())
b=bin(t).lstrip('0b')
b='0'*(6-len(b))+b
s='0b'+b[0]+b[5]+b[3]+b[2]+b[4]+b[1]
print int(s,2)
