Problem 3: Textbook Exercise 1.68 Ben Bitdiddle and Alyssa P. Hacker are having another argument. Ben says, I can get the two's complement of a number by subtracting 1, then inverting all the bits of the result." Alyssa says, "No, I can do it by examining each bit of the number, starting with the least significant bit. When the first 1 is found, invert each subsequent bit." Do you agree with Ben or Alyssa or both or neither? Explain
