Add Two Integers

Problem Statement

Given two integers num1 and num2, return the sum of the two integers.

Examples

Example 1:

Input: num1 = 12, num2 = 5
Output: 17
Explination: num1 is 12, num2 is 5, and their sum is 12 + 5 = 17, so 17 is returned.

Example 2:

Input: num1 = -10, num2 = 4
Output: -6
Explination: num1 + num2 = -6, so -6 is returned.

Constraints

• -100 <= num1, num2 <= 100

Solution

C++ Implementation

class Solution {
public:
    int sum(int num1, int num2) {
       return num1 + num2;
     }
};

Python Implementation

class Solution:
    def sum(self, num1: int, num2: int) -> int:
        return num1 + num2

Java Implementation

class Solution {
    public int sum(int num1, int num2) {
        return num1 + num2;
    }
}

JavaScript Implementation

    var sum = function(num1, num2) {
      return num1 + num2;
};

TypeScript Implementation

    function sum(num1: number, num2: number): number {
         return num1 + num2;
};

Conclusion

These implementations handle the addition of two integers and return their sum. The examples provided also show how to use each function. The problem is straightforward and has a constant time complexity of 𝑂(1) for each implementation.
