Sum of Two Integers

Given two integers a and b, return their sum without using the + or - operators.

Input:

1
2

Output:

Reasoning:

First, we initialize the sum to 0 and store the input values a = 1 and b = 2.
Then, we use bitwise operations to add the numbers: a ^ b calculates the sum without considering the carry ( $1 ^ 2 = 3$ ), and a & b calculates the carry ( $1 & 2 = 0$ ).
Since there's no carry ( $0$ ), the final result is just the sum from the XOR operation: $1 ^ 2 = 3$ .
The final output is $3$ .
