Did you know?

Searching in a binary search tree for a specific key can be programmed recursively or iteratively. Searching begins by examining the root node. If the tree is nil, the key being searched for does not exist in the tree. Otherwise, if the key equals that of the root, the search is successful and the node is returned. If the key is less than t… WebTree (data structure) This unsorted tree has non-unique values and is non-binary, because the number of children varies from one (e.g. node 9) to three (node 7).
