title: Remove a character at an index position in Ruby
body: <p>Basically what the question says. How can I delete a character at a given index position in a string? The String class doesn't seem to have any methods to do this.</p>
  
  <p>If I have a string "HELLO" I want the output to be this</p>
  
  <pre><code>["ELLO", "HLLO", "HELO", "HELO", "HELL"]
  </code></pre>
  
  <p>I do that using</p>
  
  <pre><code>d = Array.new(c.length){|i| c.slice(0, i)+c.slice(i+1, c.length)}
  </code></pre>
  
  <p>I dont know if using slice! will work here, because it will modify the original string, right?</p>
