371.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:









function getSum(a, b) {
  while (b != 0) {
    let carry = a & b;
    a = a ^ b;
    b = carry << 1;
  }

  return a;
}
