Webb6 apr. 2024 · A red-black tree is a special type of binary search tree where each node has a color attribute of red or black. It allows efficient searching in the list of child objects under a storage object. The constraints on a red-black tree allow the binary tree to be roughly balanced, so that insertion, deletion, and searching operations are efficient. WebbIn Red black tree if imbalancing occurs then for removing it two methods are used that are: 1) Recoloring and 2) Rotation. To understand insertion operation, let us understand the keys required to define the following nodes: Let u is newly inserted node. p is the parent node of u. g is the grandparent node of u.
