What happened to the index of a list when elements are add/removed?
<p>I've a list of strings <strong>Dad</strong>, <strong>mam</strong>, <strong>Junior</strong>, <strong>Richard</strong>. Let's say, I remove Junior whose index is <strong>2</strong> from the list. Is richard's index becomes 2 or is still 3 with a gap at the second position?</p>

<p>Thanks for helping</p>
