Is there a way to put strings in the `string.insert("", "")` function?
<p>So here's the line of my code to which I'm referring:</p>

<pre><code>x.insert("a", "hello");
</code></pre>

<p>I'm trying to insert the string "hello" after each "a" in a string. Is it possible to do this with the <code>insert</code> function?</p>
