Convert sorted list to Binary Search Tree
OJ: https://oj.leetcode.com/problems/convert-sorted-list-to-binary-search-tree/
Given a singly linked list where elements are sorted in ascending order, convert it to a height balanced BST.
Idea: Use the intermediate point as the root node and create it in the FIFO order.
/** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *nex
When a number is used in binary or hexadecimal notation, the inverse of this number is actually usedThe inverse of a number, that is, the inverse of the code, the resulting value is the inverse codeIn the C language, negative numbers are stored in the form of a complement, and the calculated method is the binary value of the negative value corresponding to the value, followed by a bitwise negation.When a ne

The
topic is very simple, give you a binary tree after the order and the sequence, to find its pre-order sequence (so easy!).
Input
input has multiple sets of data (less than 100 groups), ending with the end of the file.
Each group of data is only on
Title Description:
Converts the number of M-binary x to the number output of n-binary.
Input:
The first line of input consists of two integers: M and N (2The following line enters a number x,x is the number of M-binary, and now requires you to convert the M-binary
LeetCode 111 Minimum Depth of Binary Tree (Minimum Binary Tree Depth) (BT, DFS )(*)Translation
Given a binary tree, find its shortest depth. The shortest depth refers to the shortest distance from the node to the nearest leaf node.
Original
Given a binary tree, find its minimum depth.The minimum depth is the number of
C Language Search Algorithm order lookup, binary search (binary find), the recent test to use, the Internet also has a lot of examples, I think I wrote to understand some.
Sequential Lookup/*Sequential Lookup order lookups are the exact locations of the same number of given keywords in a known no (or ordered) Order queue. The principle is to have the keyword match the number in the queue from the last o

A Tree is a finite set of n (n ≥ 0) nodes. In any non-empty tree:
(1) There is only one specific Root node;
(2) When n> 1, the remaining nodes can be divided into m (m> 0) finite sets T1, T2 ,..., Tm, where each set is itself a tree, and is called

Binary Search is a frequently used algorithm in Ordered arrays. When you are not in contact with the binary search algorithm, the most common method is to traverse the array, compare with each element. The time is O (n ). but the
Given a non-empty binary search tree and a target value, find K values in the BST that is closest to the target.Note:
Given target value is a floating point.
Assume k is always valid, which is: k ≤total nodes.
You is guaranteed to a unique set of K values in the BST is closest to the target.
Follow up:Assume that the BST are balanced, could you solve it in less than O(n) runtime (where n = Total nodes)?Hint:1. Consider implement
Given A binary search tree (BST), find the lowest common ancestor (LCA) of the Given nodes in the BST.According to the definition of the LCA in Wikipedia: "The lowest common ancestor is defined between," nodes V and W as the L Owest node in T, have both V and W as descendants (where we allow a node to be a descendant of itself).
