## Description
|
|
<section id='description'>
|
|
<code>if/else</code> statements can be chained together for complex logic. Here is <dfn>pseudocode</dfn> of multiple chained <code>if</code> / <code>else if</code> statements:
|
|
<blockquote>if (<em>condition1</em>) {<br> <em>statement1</em><br>} else if (<em>condition2</em>) {<br> <em>statement2</em><br>} else if (<em>condition3</em>) {<br> <em>statement3</em><br>. . .<br>} else {<br> <em>statementN</em><br>}</blockquote>

## Instructions
|
|
<section id='instructions'>
|
|
Write chained <code>if</code>/<code>else if</code> statements to fulfill the following conditions:
|
|
<code>num < 5</code> - return "Tiny"<br><code>num < 10</code> - return "Small"<br><code>num < 15</code> - return "Medium"<br><code>num < 20</code> - return "Large"<br><code>num >= 20</code> - return "Huge"
