title: Is any other quickest to print the same result?
body: <p>Code:</p>
  
  <pre><code>arr = [[1,2,3],[4,5,6],[7,8,9]]
  a=0
  b=0
  while b &lt;= 2
      a=0
      while a &lt;= 2
      print arr[a][b]
      a+=1
      end
  b+=1
  puts " "
  end
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>147
  258
  369
  </code></pre>
  
  <p>Is there a quicker way of achieving the same result?</p>
  
  <p>I am just a beginner, so don't make it too had.</p>
