WebDec 13, 2024 · Let the input number be n. n-1 would have all the bits flipped after the rightmost set bit (including the set bit). So, doing n&(n-1) would give us the required result. So, now let us see how n – 1 is flipping all the bits to the right (including the rightmost set bit also) of the n. Taking n = 12, so (n – 1) = 11, WebA bit flip of a number x is choosing a bit in the binary representation of x and flipping it from either 0 to 1 or 1 to 0.. For example, for x = 7, the binary representation is 111 and we may choose any bit (including any leading zeros not shown) and flip it. We can flip the first bit from the right to get 110, flip the second bit from the right to get 101, flip the fifth bit … WebOct 31, 2013 · This question would be more interesting if you were asking to invert only bits 0..the most significant bit, for any given int. – mbeckish.
