The existence of binary search trees implies the existence of a Non Binary Search Tree...

Urgh, the photo quality is terrible, I need to figure out this studyblr stuff... Anyway, I picked a random topic to revise today, namely search algorithms for OCR A level computing. Not too difficult, just some pseudo code and maths. Essentially if your data is sorted, use binary search, if not, sort it then use binary search. (I guess linear search works in some cases). I only showed a recursive algorithm for binary search, since I prefer it. This is my first study post, please tell me what you think! Tips to improve the lighting would be much appreciated, or any other advice for that matter.

What is a binary search tree in Data structure?

Binary search tree is a class of Binary trees in which all nodes are arranged in a specific order. A binary search tree is also called an ordered binary tree. 

 Features of Binary search tree:

  In a binary search tree, each node in the left subtree has a value less than or equal to the value of the root.

  In the same way, each node on the right subtree has a value greater than or equal to the value of the root.

 This rule is repeated to all the right and left subtrees until it ends.

이진 탐색 트리(Binary Search Tree)

데이터를 찾아보자! 이번에는 이진 탐색(Binary Search)이 적용된 이진 트리(Binary Tree)에 대해서 알아볼 것입니다. 이진 트리(Binary Tree)에 대해 더 상세한 설명을 보고싶으시면 아래 링크를 방문하여 이진 트리에 대한 설명을 읽어보시기 바랍니다. 이진 트리(Binary Tree) 우리가 알고 있는 이진 트리는 자식 노드가 최대 두 개의 노드를 지니고, 네 가지 성질을 지닙니다. 자식 노드가 아에 없거나, 왼쪽 자식 노드 혹은 오른쪽 자식 노드 하나만 존재하거나, 왼쪽과 오른쪽 자식 노드를 모두 지니는 경우입니다. 그렇다면, 우리가 배우게 될 이진 탐색 트리는 어떻게 자라야 할까요? 가장 핵심은 왼쪽 자식 노드가 부모 노드보다 작고, 오른쪽 자식 노드는 부모 노드보다…

Find the nearest integer of a given number in the binary search tree.

Find the nearest integer of a given number in the binary search tree.

Given a Binary Search Tree (BST) contains integers and an integer. We aim to find the nearest node to input integer in the BST. Let us understand this with an example.

We have given a binary search tree root node and a target(14) as showing in picture.

Let’s see how our solution works to get the nearest node to the target integer.

We store the diff (4) which we consider as minimum for now…

資料結構 – 二元樹 ( Binary tree )

二元搜尋樹 Binary search tree 又叫做有序二元樹， 二元搜尋樹的特性為：

任何節點的左子樹不為空，則其左子樹的所有值均比其樹根小

任何節點的右子樹不為空，則其右子樹的所有值均比其樹根大

任意節點的左右子樹均為二元搜尋樹

底下就是一個二元搜尋樹(圖片取自維基百科)

二元樹有幾個特殊名詞： 滿二元樹 ( Full binary tree )：特性為每一層的節點都有最大節點數，假設樹高為 n ，節點數量必為 2 的 n 次方 -1 完全二元樹 ( Complete Binary Tree )：假設樹高為 n ， n-1 層擁有最大節點數量，第 n 層節點從缺少的節點開始到該層結束都為空 葉節點 ( Leaf ) ： 沒有子節點的節點稱為葉節點 根節點 ( Root )： 沒有父節點的節點稱為根節點

二元樹的走訪 (Traversal) 可分為： 前序 (…

Binary Search Tree to Greater Sum Tree

Leetcode question

Given the root of a binary search tree with distinct values, modify it so that every node has a new value equal to the sum of the values of the original tree that are greater than or equal to node.val.

As a reminder, a binary search tree is a tree that satisfies these constraints:

The left subtree of a node contains…
