Repeat Problem 3-52, assuming the numbers are 2s complement signed numbers. Use extension to equalize the length of the operands. Indicate whether overflow occurs during the complement operations for any of the given subtrahends. Indicate whether overflow occurs overall for any of the given subtractions. When an overflow does occur, repeat the operation with the minimum number of bits required to perform the operation without overflow.

Problem 3-52 questions:

(a) 11010 - 10001

(b) 11110 - 1110

(c) 1111110 - 1111110

(d) 101001 - 101
