I am referring to this problem: Determining DNA Health. The editorial mentions using Aho- Corasick Algorithm. I was wondering can it be solved using tries?

I am the setter of this problem. The Aho-Corasick automaton I mention in the editorial is a trie itself (it is created by adding the suffix links to trie nodes). So, in a way, that problem is solved using tries only.
Hi! Thanks for the reply. I couldn't quite get the editorial because I am new to this data structure. Can you direct me to some good resources which I should refer to so that I can understand the editorial? Thanks for your efforts.
I learnt from here.
