title: Most common values in an array
body: <p>How would I go about finding the three most common elements in an array? I am working with an array of length 10,000 with elements = random integer from 0-100.</p>
  
  <p>I was thinking of using two arrays, one of length 100 and just incrementing by using an if statement. However, I was wondering if there is a way that only one for/if loop(statement) could be used to find these values.</p>
