WebNov 2, 2024 · To find the number of bits in a number, we must count the number of steps taken to go from x to 0 by turning the maximum number of the rightmost bits off in a step. Where x is a number in the range [0, N]. Approach: This will be done by the bitwise-and operation between x and x – 1. WebMar 24, 2024 · Simply put, the task is to find the total number of 1’s(set bits) in the integer. Example 1 Input Given Integer (N) = 15 Output Count of set bits in 15 = 4 Explanation The binary representation of 15 looks like this: 15 = 23+ 22+ 21+ 20= 8 + 4 + 2 + 1 = 15 So, the total number of set bits, i.e., the total number of bits with value one is 4. medford nursery roses
