// tips to avoid bugs.

/*
  * be careful of whats happening you dont want a continue statement to miss imp line of code.
  * be careful when to update what since it might be needed in next segment of code.
  * dont get stuck on one idea.
  * dont use too much space bar so that code is written quickly as possible.
