The question is as such
You are given string s1 = “” and a string s2 = “abcbcaa”
You can perform any one of the two operations on s1 :
Append a new character to s1. This costs you A dollars.
or
Append an existing substring of s1 to s1. This costs you B dollars.
Find the minimal dollars you need to pay in order to convert s1 to s2
This is not from any ongoing contest you can find it here
