Summary:Ordinary BST does not guarantee a good performance after multiple operations. So we need a BST, yes. The cost of each insertion and search is a logarithmic function of the large size of the tree. The 2-3-4 tree is a kind of BST that maintains balance.2-3-4 Tree IntroductionTo ensure that BST is balanced, we nee
