Hello,

Your question is not clear dear. But I'll provide some problems about bubble sort. If you are giving any examination in now days everything will be bubble sort fill up including. Like your name or specially your roll no etc. The worst case in here if you didn't match your roll no with bubbles than sometimes your examination will cancel because it's not scanning by the computer. Like every answer sheet have different series of numbers wih bubbles. So whenever you fill this up please be careful. And take your own time then fillup it. If any problem is occure but remember don't do any mistake but if occur then immediately talk to the hall examiner. But always be careful.

All the best.
