Practice Snakes and Ladders
Master the Snakes and Ladders LeetCode problem with undetectable real-time assistance. Get instant solutions and explanations during your coding interviews.
PhantomCodeAI generates complete solutions and debugging hints that you can use while explaining your approach, so you stay calm and in control.
Snakes and Ladders
The n by n board is numbered 1 through n^2 starting at the bottom-left, reversing horizontal direction on each higher row. Begin at square 1. Each roll chooses a square from curr + 1 through min(curr + 6, n^2). If that square has a snake or ladder, immediately move to its indicated destination; follow at most one such link per roll, even if its endpoint has another. A cell value of -1 means no link, and squares 1 and n^2 have none. Return the fewest rolls to reach n^2, or -1 if it cannot be reached.
