title: Can you store multiple integers at one array index?
body: <p>I'm trying to do a radix sort and some algorithms I've seen have a buckets[ ] array that's supposed to hold multiple integers into one index of the bucket array, here is the algorithm I'm referring to: <br><br><img src="https://i.stack.imgur.com/03CAT.png" alt="here is the algorithm I'm referring to" /></p>
  <p>Is it really possible to have multiple integers in one index? And how so?<br>
  Or is there a simpler radix sort algorithm out there?</p>
