Solution (in PYTHON3):

Solution:


# n = int(input())
def solve(n):
    bits = []
    for i in range(6):
        bits += [n % 2]
        n //= 2
    bits = bits[::-1]

    p = [0, 5, 3, 2, 4, 1]

    new_bits = [0] * 6
    for i in range(6):
        new_bits[p[i]] = bits[i]

    res = 0
    for i in new_bits:
        res *= 2
        res += i
    return res

# print(solve(2))
# print(solve(5))
# print(solve(35))


print(solve(int(input())))
