1a) Suppose you have the following two bytes: 00001001 and 01100101. What is the 1s complement of the sum of these two bytes?

1b) Suppose you have the following two bytes: 01101001 and 11101101. What is the 1s complement of the sum of these two bytes?

1c) For the bytes in part (1a), give an example where one bit is flipped in each of the two bytes and yet the 1s complement of the sum doesnt change.
