An encode (A) function is being designed to receive a sequence of digits in A string parameter, and return a sequence of number (also in string) which has been encoded with below encoding table. 0 1 2 3 4 4 5 5 6 6 7 8 9 Original Digit Encoded Digit 1 5 7 0 3 9 2 CO 4 00 Example of how encode (A) function can be used is shown below. A = "8643" B = encode (A) | print (B) # "4260" will be printed out. Codes of partial working encode (A) function are given below, but contain some errors. List and state all the errors in the codes. def encode (A): i = 1 while i
