Find the shortest distance from the node in B to any point V on the tree d[v], when and only if the distance of red token to V is l

Twitter's real-time search engine started in a small company that was acquired, and as traffic grew, functions increased and service objects expanded, search engines continued to face new challenges and the design went through many changes. This presentation will introduce the challenges and decisions in the evolution of this real-time search engine.Wang Tian, Twitter Senior staff Engineer, 2003 Tsinghua Computer Department graduated and went to the United States to study, 2005 after the master'

670. Maximum Swap Given a non-negative integer, you could swap two digits in most once to get the maximum number. Return the maximum valued number to could get. Example 1: input:2736 output:7236 Explanation:swap The number 2 and the number 7. Example 2: input:9973 output:9973 explanation:no swap. Given a nonnegative number, swap the two digits in the number to get the maximum number. Idea: See code comments Code: Package Array; /** * @Author oov

Idea: With a stack structure, the num of int is converted to a vector for storage. With the help of a vector, the elements inside the previous vector are sorted by a large to small sort. Compare these two vectors from 0-size () to determine the

strength to implement also use the Docommonmath method. Another aspect of this transplant is also noteworthy. By using JavaScript, a user can assign a dynamically determined value to an instance variable, such as: var PiD2 = Pi ()/2 You cannot do this in PHP. You can only assign simple constant values to instance variables. It is hoped that this flaw will be solved in the PHP5. Note that the code in Listing 1 does not define instance variables-This is because they are dynamically assigned

feature of this implementation is the Docommonmath method, which all the functions in the library reuse. Other tests (normal and Chi-square) that I don't have the strength to implement also use the Docommonmath method. Another aspect of this transplant is also noteworthy. By using JavaScript, users can assign dynamically determined values to instance variables, such as: var PiD2 = Pi ()/2 This cannot be done in PHP. You can assign a simple constant value to an instance variable only. Hopefully,

distribution functions has all the functions I need. for ease of learning, these functions are implemented in JavaScript. I transplanted Student T and Fisher F functions to PHP. I made some changes to the API to conform to the Java Naming style and embed all functions into the class named Distribution. A great feature of this implementation is the doCommonMath method, which is reused by all functions in this library. The doCommonMath method is also used for other tests (normality and chi-square
