If we have to delete element 7, we will have to traverse all the elements to find it, therefore performingdeletionin a binary tree, the worst-case complexity= O(n). Complexity of Searching, Insertion and Deletion in Binary Search Tree (BST) Binary Search Tree (BST) is considered as a s...
In this algorithm deletion, insertion etc. operations are used to prioritize among nodes with different values. We combine these operations using a BST as a priority queue. This algorithm also uses the term probability of survival, which indicates the probability of a person surviving. A flexible...

12.3 -Insertion/Deletion - Same as 12.2 12.4 -Randomly built BSTs - just know Theorem 12.4 (expected height of random BST is O(lgn)) and an idea of why it's true. Chapter 13 This one is easy. Know what a Red-Black tree is, and what its worst-case height/insert/delete/find are....

如果忘记了BST的性质,先去上面复习一下 Insertion 和 Deletion 的操作。13.1. RotationWhen we do a left rotation on a node x, we assume that its right child y is not T:nil; x may be any node in the tree whose right child is not T:nil. The left rotation “pivots” around the link ...

Insertion, deletion min/max, and build. Insertion: we insert the node into the leaf, and max(min)heapify the heap to restore the ordering, the worst case run time is O(nlogn). Deletion: swap the node that was intended to be deleted (usually the root for max or min element) with ...
