WebBit Hacks – Part 1 (Basic) Swap two numbers without using any third variable. Problem 1. Check if an integer is even or odd. This is probably one of the simplest and most … 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,
