index. For example, the user queries Abstract: System and Email: The abc@mit.edu results in all files that contain System in the abstract and have a abc@mit.edu in the e-mail address. That is to say, if you search for the index in the inverted table, doc15 is returned. Files that match the query are listed according to the number of times the term appears in the file and the number of documents containing

Balanced Binary Tree (Java code failed, why ???), Balancedbinary Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two s

Defines the decimal number direct write, the number of the definition 8 to start with 0, defines the binary number to start with 0b, defines the hexadecimal number to begin with 0xYou need to represent the decimal number as a binary number in order to refer to the following example:int a = ten; System.out.println (Integer.tobinarystring (a));Convert binary into o

Binary representations of Java-printed integers (code and parsing)int a=-99;for (int i=0;iIn order to understand the problem of this shift output, you need to understand the following:* 0x80000000 is the hexadecimal representation of the number, which is converted to binary representation as 100000000000000000000000000

Java Dynamic Programming-Example code for distance editing and java sample code The dynamic planning process is: each decision depends on the current state, and then causes the state transfer. A decision sequence is generated in a changed state. Therefore, this multi-stage o

The balanced binary sort tree inserts a new element recursive algorithm, or more complex, especially the implementation of the code want to understand or to go step-by-step to manually execute the code. Personally understand this algorithm and look at the sample code is also a lot of effort, understanding level is stil

the index by words. Because we usually want to store the location of the file, but rarely use the file name as the keyword to search, so we use this field to index the Java file name. The unstored field is opposite to the unindexed field. This type of field will be analyzed and indexed, but its value will not be saved to the index. Because the entire source code

(patterns) and text (text) in the matching process with known information. The posting bad character algorithm (Bad-character) and the Good suffix Algorithm (good-suffix), which are recommended above, are used to determine how many bits to move (shift) or move, not to elaborate here. Full algorithm: because this article is mainly used to help remember, not the persuasion to tell you how to implement this algorithm. So I put the complete code (
