Question: Assume N is an unsigned 3 2 - bit integer, N > 0 , what does the following bitwise operation do ? N = N

Assume N is an unsigned 32-bit integer, N >0, what does the following bitwise operation do?
N = N & (N-1)
Group of answer choices
It sets the leftmost 1 to 0 in the 32-bit representation
It flips all 0s to 1s in the 32-bit representation
