Write a function add_bytes (b1, b2) that takes as inputs two strings b1 and b2 that represent bytes (i.e., 8-bit binary numbers). The function should compute the sum of the two bytes and return that sum in the form of a string that represents an 8-bit binary number. For example: >>> add_bytes('00000011', '00000001') '00000100' >>> add_bytes('00011100', '00011110') '00111010' Note that you will need to ensure that the result is exactly 8 bits long. If the result is too short, you should add Os on the left-hand side to get a string that is 8 characters long. If the result is too big to be represented in 8 bits, you should return the rightmost 8 bits of the result. For example: >>> add_bytes('10000011', '11000001') # the result (101000100) has 9 bi '01000100' Here again, you should not use recursion or perform any binary arithmetic. Rather, you should make use of the conversion functions that you wrote for problem 1. Hint: To ensure that your result has the correct length, we encourage you to do the following: - Use your conversion functions to determine the binary representation of the sum, and store that result in a variable. - Determine the length of the result using the len() function, and store that length in a variable. Then you can use conditional execution (if-else or if-elif-else) to decide what you should return. - If the result is less than 8 bits long, precede the result with the correct number of leading '0's. You can use the multiplication operator to produce the necessary string of '0's. Make sure that you also handle the case in which the result is more than 8 bits long
