hello codeforces, today I have a really interesting question for you.

what does the phrase "Aho–Corasick is a based algorithm" mean to you?

  • algorithm is good
  • Depends on the context
  • Algorithm is bad
  • I don't know the word "based"

I want to know it to understand if there is a difference between Russian and English word "based".
