WebNov 14, 2024 · If rightmost set bit is not at the end (LSB), we are simply right-shifting the rightmost set bit If rightmost set bit at the end - We consider all 1s at the right-end as a single group. Then we find a rightmost set bit that is not part of this group and shift it 1 position to the right (see how mask is updated at step-3, 5, 6). WebStep 1: Unset the rightmost bit of number n. To unset the rightmost bit of number n: Subtract one from n. The idea is that when we subtract one from an integer, all the bits following the rightmost set bits are inverted, turning 1 to 0 and 0 to 1. Perform AND (&) operation on the result of step 1 and n.
