title: Generating unique random numbers except from a specific one in C
body: <p>I was wondering, how can I generate unique random numbers except from a specific one. For example, if I want to generate numbers in range <code>1 to 10 except from 3</code>, the output should be something like this:</p>
  
  <pre><code>7 6 1 2 4 9 5 8 10
  </code></pre>
