title: Regex to match any integer greater than 1
body: <p>I recently just picked up on regex and I am trying to figure out how to match the pattern of any numbers greater than 1.
  so far I came up with</p>
  
  <pre><code>[2-9][0-9]*
  </code></pre>
  
  <p>But it only works with the leftmost digit not being 1. For example, <code>234</code> works but <code>124</code> doesn't. </p>
  
  <p>So what am I trying to achieve is that a single digit of <code>1</code> shouldn't be matched and any integer greater than it should.</p>
