def str_to_hex(s):
    return ' '.join([hex(ord(c)).replace('0x', '') for c in s])

def hex_to_str(s):
    return ''.join([chr(i) for i in [int(b, 16) for b in s.split(' ')]])

def str_to_bin(s):
    return ' '.join([bin(ord(c)).replace('0b', '') for c in s])

def bin_to_str(s):
    return ''.join([chr(i) for i in [int(b, 2) for b in s.split(' ')]])
