I guess you forgot to give the "following words" :)
you need to try concatenations all possible words from L
that means you need to Generating all possible Subsequences
read this blog to know how to do that https://www.geeksforgeeks.org/generating-all-possible-subsequences-using-recursion/
after that check the following words **[I think it's from input as I guess] if it included on it.
to it's look like this
Thank you a lot
you're welcome
