title: Understanding Project Euler #31
body: <p>Could anyone explain me <a href="http://projecteuler.net/index.php?section=problems&amp;id=31" rel="nofollow noreferrer">problem 31 of project euler</a>? I don't understand the problem clearly.</p>
  
  <p>Is the problem saying to calculate the coins in any order like:</p>
  
  <p><strong>2*£1</strong> or perhaps <strong>1×£1 + 1×50p + 2×20p + 1×5p + 1×2p + 3×1p</strong> ?</p>
