additon without plus and minus operator.txt

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

    }
};
