WebThe total number of set bits between 0 and 2^n excluded is 2^(n-1)*n. Because in this particular case, 50% of bits are set in each column and other 50% are unset, and there is n columns. For a number A which is not a power of 2, we can break down the calculation into several passes, one for each set bit in the number A in question, and use the ... WebThis works as the expression n-1 flips all the bits after the rightmost set bit of n, including the rightmost set bit itself. Therefore, n & (n-1) results in the last bit flipped of n .
