This article introduces the relevant knowledge of "how to calculate the number of bits 1 in c++". In the operation process of actual cases, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

Question 1: Count the number of bits 1

Code implementation:

func hammingWeight(num uint32) int { count := 0 for i := 0; i

4// 0000 1000 ->8// 0001 0000 ->16// 0010 0000 ->32// 0100 0000 ->64// 1000 0000 ->128

Question 3: Sum of two integers

Code implementation:

func getSum(a int, b int) int { // b as a carry, when 0, indicates the end of calculation for b != 0 { sum := a ^ b carry := (a & b)
