These two days are paging and learningTwo TypesImplementation Method: (describe the main technologies used in my project: Ajax + JSON + Action + JDBC + JS) The first method is to retrieve the amount of data required. The implementation of paging

Give you a tree. Each node has a number. Ask you to find a node. There are several nodes with numbers smaller than him in his subtree. (The ID is unique. From 1-N, the root node has been given) Solution: Tree array statistics. Convert to

Function 1: sum (x) returns the Range Sum of the original array [1, x]. Update (x, W) adds W to the number of the original array subscript X.These two functions use the O (logn) time and O (n) Space to complete the single point addition and

Phototype in JS is a more difficult part of Js.   This article is based on the following knowledge points:   1 original method design mode In. net, you can use clone () to implement the original method. The main idea of the original method is that

The project needs to splice a table in JS. Some code is as follows: VaR result = " "+" "+" "+" "; result + = "" + " employee ID " + " name "+" Department "+" position "+" skill level "+" contact number "+" nationality "+" Current

Two methods are provided here. I prefer the first one. First: Define an array in JS VaR nations = ["Han", "Mongolian", "Hui", "Tibetan", "Uygur", "Miao", "Yi", "Zhuang", "Buyi ", "Korean", "Manchu", "Dong", "Yao", "bai", "TuJia", "Hani", "Kazakh", "

A queue is used to save the order of traversal nodes, while a stack stores the parent node of the currently traversed node. Simulated process: http://acm.hdu.edu.cn/showproblem.php? PID = 1, 4041 1): Number the node name once during the simulation
