python code

Problem 2. Consider the following code to encode a text string as a binary string using ASCII. def encode (X): Y=str() for x in X: Y=Y+str(format (ord(x), '08b')) return Y def decode(Y): X=str() while len(Y)>0: temp=Y[:8]; YEY[8:] X = X + chr(int (temp, 2)) return X def XOR (A,B): temp = int(A, 2) **int(B,2) return bin(temp) [2:] .zfill(len (A)) You will receive four ciphertexts via email that were encrypted using the same one-time pad. Find the original plaintext messages. ciphertexts: C1='1000011010010011001010011101001010110100101010110000100001111111110011000111001110001 01011101000101010100110011000101101100011111011100000010101101101010100111000101101011111 10011000101100010111000111" C2="10000110100100110010010110000001111110011010110100010100001100011000001101110100100 10101101100011110100001101011011110001001101111101101000010001011100101001011011001000110 1101011011111100001010011101 C3="100001011001001000101100110011011011010010111011000101000010101010000011011111111001 0100111110001110010001100000001011011001011110111001010111001010001001001010001011010110 0111011000101000100110001100 C4='10000110100100110010010110000001111101111010101000010010001111001100100001111000100 0100010110001111000110111010000101101100101111010001101011100101000100100110101101000001 01010011101111101100111000111
