that is a classic textbook dynamic programming (or suffix tree, depends on the size of the set) problem. behind the puzzle, it is the thought about dividing one bigger problem into smaller ones, and hence solve them with code efficiently. maybe that does not sound too far from your day-to-day coding. the site probably should have presented these puzzles from a different perspective, so that it is easier for people to recognize the message about what kind of programmer skills and mindset it is looking for. |
