Task
You are taking part in an Escape Room challenge designed specifically for programmers. In your efforts to find a clue, you’ve found a binary code written on the wall behind a vase, and realized that it must be an encrypted message. After some thought, your first guess is that each consecutive 8 bits of the code stand for the character with the corresponding extended ASCII code.
Assuming that your hunch is correct, decode the message.
Example
For code = "010010000110010101101100011011000110111100100001", the output should be
messageFromBinaryCode(code) = "Hello!".
The first 8 characters of the code are 01001000, which is 72 in the binary numeral system. 72 stands for H in the ASCII-table, so the first letter is H.
Other letters can be obtained in the same manner.
Input/Output
-
[execution time limit]
4 seconds (py3) -
[input] string code
A string, the encrypted message consisting of characters'0'and'1'.
Guaranteed constraints:0 < code.length < 800. -
[output] string
The decrypted message.
My Solution
def messageFromBinaryCode(code):
message = ''
for i in range(len(code) // 8):
message += chr(int('0b' + code[8 * i:8 * (i + 1)], 2))
return message
