    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, ) 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, ) for b in s.split(' ')]])
