Problem
-------
https://leetcode.com/problems/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``
