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 $0$s to $1$s in the $32-$bit representation

It sets the rightmost $1$ to $0$ in the $32-$bit representation.

It is same as N $-1$
