用pseudocode的形式的话,就是这样: 1 2 3 4 5 6 7 8 9 PREORDER-WALK(x) 1if(x!=NIL) 2 PREORDER-WALK(x.left) 3 print x.key 4 PREORDER-WALK(x.right) 3. BST的几种基本操作: SEARCH, MINIMUM, MAXIMUM, PREDECESSOR, SUCCESSOR, INSERT, and DELETE. 2.1 SEARCH: 1 2 3 4 5 6 7 8...
Return the root of the updated binary search tree. Here is the pseudocode for deletion in a binary search tree: function deleteNode(root, value): if root is NULL: return root if value < root->data: root->left = deleteNode(root->left, value) else if value > root->data: root->right...
Our pseudocode for this transformation is therefore: algorithm RIGHT_ROTATE(node): // INPUT // node = the node to rotate around // OUTPUT // the tree after performing a right rotation on the given node x <- node.left node.left <- x.right x.right <- node x.color <- node.color no...
Recall that new nodes are inserted into a binary search tree at the leaves. That is, adding a node to a binary search tree involves tracing down a path of the binary search tree, taking left's and right's based on the comparison of the value of the current node and the node being i...
In this tutorial, we explained, in a nutshell, the binary tree, the binary search tree, and the tree sort algorithm. Then we showed the pseudocode of the main two functions of the algorithm; inserting a new node in newly created BST, and traversing this BST to print it in ascending orde...
Algorithms on restructuring binary search trees are typically presented in imperative pseudocode. Understandably so, as their performance relies on in-place execution, rather than the repeated allocation of fresh nodes in memory. Unfortunately, these imperative ...
There are two ways to implement a binary search. Iteration and recursive method. Iteration method pseudocode does until the least and max pointers meet. mlevel = (least + max)/2 if (x == arr[mlevel]) return mlevel else if (x > arr[mlevel]) ...

This is a largish problem for a whiteboard, the candidate who gets this question should talk it out, put some very high level pseudocode on the whiteboard to show you understand it before doing any "coding".I doubt there's an actual "best solution". My solution:Build a tree with nodes ...
Below is the pseudocode of binary search algorithm? Procedure binary_search A ? sorted array n ? size of array x ? value to be searched Set lowerBound = 1 Set upperBound = n while x not found if upperBound < lowerBound EXIT: x does not exists. set midPoint = lowerBound + ( upper...
