title: how to split this string by using regex?
body: <p>I want to split this String:</p>
  
  <pre><code>5+(4/2)-4+1+(4%3)!=23+(3*5)
  </code></pre>
  
  <p>into a list , using <code>regex</code>.</p>
  
  <p>The output should be:</p>
  
  <pre><code>[5 , + , ( , 4 , / , 2 , ) , - , 4 , + , 1 , + , ( , 4 , % , 3 , != , 23 , + , ( , 3 , * , 5 , ) ]
  </code></pre>
  
  <p>NOTE : My problem exactly is with the <code>not equal</code> operator , the <code>regex</code> does not consider it as a single character</p>
