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. Code wise: n & (n - 1) Let’s see an ... WebIf there are 0 or more than 1 set bit the answer should be -1. Position of set bit '1' should be counted starting with 1 from LSB side in binary representation of the number. Example 1: Input: N = 2 Output: 2 Explanation: 2 is represented as "10" in Binary. As we see there's only one set bit and it's in Position 2 and thus the Output 2. Example 2: WebApr 17, 2024 · Explanation − binary of 4 is 100, the index of the rightmost set bit is 3. To solve this problem, a simple solution would be shifting the number till a set bit is encountered but this could take a lot of computation if the number is large. A more efficient solution will be using boolean algebra. redo of healer manga chapter 41

WebOct 26, 2024 · So we can take any set bit, in code we have taken the rightmost set bit, iterate over it, and divide the numbers into two hypothetical buckets. If we check for numbers with that particular index bit set, we will get a set of numbers that belongs to the first bucket, also we will get another set of numbers belonging to the second bucket. WebMar 22, 2009 · Searches the source operand for the most significant set bit (1 bit). If a most significant 1 bit is found, its bit index is stored in the destination operand. The source operand can be a register or a memory location; the destination operand is a register. The bit index is an unsigned offset from bit 0 of the source operand.
