title: Remove spaces between a word and a number
body: <p>Inspired by <a href="https://stackoverflow.com/questions/26538292/remove-spaces-between-words-of-a-certain-length">this question</a>.</p>
  
  <p>How can we combine a word and a number separated by a space in a string.</p>
  
  <p>For example</p>
  
  <pre><code>There is a cooling problem in the component tx 313
  leakage found in irc 256, fixed by replacement
  Roasted cable in cpt trx235
  </code></pre>
  
  <p>The result should be</p>
  
  <pre><code>There is a cooling problem in the component tx313
  leakage found in irc256, fixed by replacement
  Roasted cable in cat trx235
  </code></pre>
  
  <p>I'm new to regex, so can't figure out a way to do it</p>
  
  <p>Thanks for the help</p>
