Sum of Two Integers

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

Constraints:

-1000 <= a, b <= 1000

public class Solution {
    public int GetSum(int a, int b) 
    {
        while (b != 0) 
        {
        int carry = a & b;
        a = a ^ b;
        b = carry << 1;
        }
        return a;
    }
}
