2235. Add Two Integers

Problem

Given two integers num1 and num2, return **the *sum* of the two integers**.   *Example 1:*

Input: num1 = 12, num2 = 5
Output: 17
Explanation: 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
Explanation: num1 + num2 = -6, so -6 is returned.

  Constraints:

• -100 <= num1, num2 <= 100

Solution (Java)

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

Explain:

nope.

Complexity:

• Time complexity : O(n).
• Space complexity : O(n).
