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

Examples

Input: a = 1, b = 2
Output: 3
Input: a = 2, b = 3
Output: 5
Input: a = 0, b = 0
Output: 0

Constraints

  • •-1000 <= a, b <= 1000
