Sum of Two Integers - LeetCode 371

 Given two integers a and b, return the sum of the two integers without using the operators + and -.

 

Example 1:

Input: a = 1, b = 2
Output: 3

Example 2:

Input: a = 2, b = 3
Output: 5

 

Solution(Only function):

class Solution {

    public int getSum(int a, int b) {

        int carry=0;

        while(b!=0){

            carry=a&b;

            a=a^b;

            b=carry<<1;

        }

        return a;

    }

}
