WebFeb 14, 2024 · Binary Search Tree Delete Algorithm Complexity Time Complexity. Average Case; On average-case, the time complexity of deleting a node from a BST is of the order of height of the binary search tree. On average, the height of a BST is O(logn). It occurs when the BST formed is a balanced BST. WebIf you are making a backtracking algorithm where going back to a previous tree is needed #1 is the only choice and it will share as much structure with the previous version of the tree. If you want to iterate and update a data structure to reflect something where you never need th eprevious state #2 is the best choice.
