Add Two Integers
Given two integers <code>num1</code> and <code>num2</code>, return <em>the <strong>sum</strong> of the two integers</em>.

<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>

<pre>
<strong>Input:</strong> num1 = 12, num2 = 5
<strong>Output:</strong> 17
<strong>Explanation:</strong> num1 is 12, num2 is 5, and their sum is 12 + 5 = 17, so 17 is returned.
</pre>

<p><strong class="example">Example 2:</strong></p>

<pre>
<strong>Input:</strong> num1 = -10, num2 = 4
<strong>Output:</strong> -6
<strong>Explanation:</strong> num1 + num2 = -6, so -6 is returned.
</pre>

<p>&nbsp;</p>
<p><strong>Constraints:</strong></p>

<ul>
	<li><code>-100 &lt;= num1, num2 &lt;= 100</code></li>
</ul>

impl Solution {
    pub fn sum(num1: i32, num2: i32) -> i32 {
        num1 + num2
    }
}
