Author here. While researching this topic I came across this article <a href="https://www.geeksforgeeks.org/compressed-tries/" rel="nofollow">https://www.geeksforgeeks.org/compressed-tries/</a> by GeeksForGeeks (compressed trie is another name for radix tree). Currently it is one of the top results on Google for this topic. Generally I've found GeeksForGeeks to be a good resource, but this article is especially poor. The code is bizarre and makes no sense:<p>- It defines properties like 'bitNumber', 'leftChild' and 'rightChild' which have nothing to do with this type of tree.<p>- The search function search(k) calls an overloaded version of itself search(root, k) that is (1) illegal in these languages and (2) not defined.<p>- The insert function does not account for all scenarios.<p>And more.<p>I'm fairly convinced this was written with the assistance of a LLM. That would be a logical explanation to all those illogical choices.
