title: Convert Hex String to Hex Value
body: <p>I have a large hex string</p>
  
  <pre><code>abcdef...
  </code></pre>
  
  <p>and I want to convert it to </p>
  
  <pre><code>0xab 0xcd 0xef 
  </code></pre>
  
  <p>Are there any functions that do that? </p>
  
  <p>Also could you tell me what I means when people ask are those inputs in ASCII or not?
  abcdef are represented as a string. Not sure if that is ASCII or not. not sure what they mean. I am very new to programming so help here would be appreciated. I have a huge string that I need to use in my array and converting it into the aforementioned format will help me initialize my array with the hex string. </p>
