Solution (in PYTHON):

Solution:
if __name__== "__main__":
    input = int(input())

    bin_input = str(bin(input))[2:]
    bin_input = bin_input.rjust(6,'0')
    string_order = [0, 5, 3, 2, 4, 1]
    bin_output = ""
    for order in string_order:
        bin_output += bin_input[order]

    print(int(bin_output,2))
