WebAug 31, 2024 · So, the total set bits in a number are 3. Input − int number = 10. Output − Count of total set bits in a number are − 2. Explanation − Binary representation of a number 10 is 00001010 and if we calculate it in 8-digit number then four 0’s will be appended in the beginning. So, the total set bits in a number are 2. Approach used in … WebSep 30, 2024 · Given a number N. Return the total number of sets bits present in the binary version of the number N. For instance, If the given number (N) = 5. Then the result is 2 because the binary version of 5 is 101. The total number of 1’s present in the 101 is 2. Hence the number of set bits is 2.
