Sum of Two Integers

Hard

Given two 32-bit integers a and b, write a function that returns the sum of a and b without using arithmetic operators ( +, -, /, etc.).

For example, given the following inputs:

a = 3
b = 12

Your function should return 15.

Try it first

def add(a: int, b: int) -> int:
    # implement add
    return -1

1def add(a: int, b: int) -> int:
2    # implement add
3    return -1
