Binary search tree delete algorithm
WebJul 6, 2015 · Let's say that you want to delete 8. You try to find largestValue from nodeToRemove.Left. This gives you 7 since the left sub-tree only has one child. Then you do: nodeToRemove.Value <- largestValue.Value Which means: 8.value <- 7.Value or 8.Value <- 7 So now your tree looks like this: 7 / \ 7 9

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.
WebFeb 20, 2024 · The above deleteTree () function deletes the tree but doesn’t change the root to NULL which may cause problems if the user of deleteTree () doesn’t change root to NULL and tries to access the values using the root pointer. We can modify the deleteTree () function to take reference to the root node so that this problem doesn’t occur.
