Implement ladderize method to avoid maximum recursion depth error #715

Closed harryrichman closed 8 months ago

harryrichman commented 8 months ago

The current ladderize method in the Tree class uses pure recursion, which can result in a RecursionError for a sufficiently large tree. If the implementation is modified to use memoization, then this recursion error could be avoided.
