"Sometimes the easiest problems teach the most important lesson: keep your solution as simple as the problem itself."
Problem
Given two integers num1 and num2, return their sum.

Example
Input: num1 = 12, num2 = 5
Output: 17
Intuition
The problem directly asks us to add two numbers.

No special data structures, algorithms, or edge cases are required.

Simply return:

num1 + num2
Approach
Take num1 and num2.
Add them together.
Return the result.
💻 Java Solution
class Solution {
public int sum(int num1, int num2) {
return num1 + num2;
}
}
