Irritating Problem statement (aaa and abb)


#1

IB team , just dont copy the problems from here and there and paste it
make the problem statement clear.
should the ith and jth character in subsequence should be there in the repeating subsequence or not.
confusing in aaa and abba


#2

starting and end indices must not be same for the subsequence. clearly aaa forms while aab does not…
