/*
some familiar issues & sugg.:
!----> [RE-READ THE CODE!]
!----> [invariants to array?]
!----> [look at global variables and their values]
!----> [llabs() for long long int type]
!----> [look at input size and time limit]
!----> [No sync with puts fn]
!----> [prefix vs suffix]
!----> [binary search? -> ubd, lbd]
!----> [array contains duplicate values!]
!----> [(a/b+1)*b vs uceil(a,b)*b]
!----> [unq_v for vec only]
