/*
Self notes cause I need it :
1. dumbfk read the question properly ... I m fed up with this lack of presence of mind
2. dont assume that something is given in question ,like the input is sorted or stuff
   if some step needs the input to be sorted , either check question or sort , dont assume
3. in case you have less time to debug : 
	Common errors :
	  -> Wrote wrong variable names at places cause ur stupid	
	 -> For debugging u hard coded small values and submitted that solution right away
