Trie implementation

由 拈花ヽ惹草 提交于 2019-11-27 13:53:58
问题 I am attempting to implement a very simple Trie in Java that supports 3 operations. I'd like it to have an insert method, a has method (ie is a certain word in the trie), and a toString method to return the trie in string form. I believe I have insertion working properly, but has and toString are proving to be difficult. Here's what I have so far. The trie class. public class CaseInsensitiveTrie implements SimpleTrie { //root node private TrieNode r; public CaseInsensitiveTrie() { r = new

Implementing a Patricia Trie for use as a dictionary

由 [亡魂溺海] 提交于 2019-11-27 10:23:47
问题 I'm attempting to implement a Patricia Trie with the methods addWord() , isWord() , and isPrefix() as a means to store a large dictionary of words for quick retrieval (including prefix search). I've read up on the concepts but they just aren't clarifying into an implementation. I want to know (in Java or Python code) how to implement the Trie, particularly the nodes (or should I implement it recursively). I saw one person who implemented it with an array of 26 child nodes set to null/None. Is

JSLint says “missing radix parameter”; what should I do?

I ran JSLint on this JavaScript code and it said: Problem at line 32 character 30: Missing radix parameter. This is the code in question: imageIndex = parseInt(id.substring(id.length - 1))-1; What is wrong here? Jayendra It always a good practice to pass radix with parseInt - parseInt(string, radix) For decimal - parseInt(id.substring(id.length - 1), 10) If the radix parameter is omitted, JavaScript assumes the following: If the string begins with "0x", the radix is 16 (hexadecimal) If the string begins with "0", the radix is 8 (octal). This feature is deprecated If the string begins with any

Using Javascript parseInt() and a Radix Parameter

由 拈花ヽ惹草 提交于 2019-11-27 04:44:27
问题 Can anyone explain how the parseInt() functions works and what the Radix Parameter is? As a case study, I am trying to get to grips with this code snippet: var maxChars = parseInt( formField.attr('maxlength') ? formField.attr('maxlength') : counter.text() ); Can you also explain how this code works? Why is formField.attr('maxlength') there twice? I find the use of operators here pretty darn confusing! How does the Radix Parameter work in this example? 回答1: The radix is another name for base ,

Radix Sort for Negative Integers

由 假如想象 提交于 2019-11-27 04:40:51
问题 I am trying to implement radix sort for integers, including negative integers. For non-negative ints, I was planning to create a queue of 10 queues correspondingly for the digits 0-9 and implement the LSD algorithm. But I was kind of confused with negative integers. What I am thinking now, is to go ahead and create another queue of 10 queues for them and separately sort them and then at the end, I will gave 2 lists, one containing negative ints sorted and the other containing non-negative

What is the radix parameter in Java, and how does it work?

I understand that radix for the function Integer.parseInt() is the base to convert the string into. Shouldn't 11 base 10 converted with a radix/base 16 be a B instead of 17 ? The following code prints 17 according to the textbook: public class Test { public static void main(String[] args) { System.out.println( Integer.parseInt("11", 16) ); } } When you perform the ParseInt operation with the radix, the 11 base 16 is parsed as 17, which is a simple value. It is then printed as radix 10. You want: System.out.println(Integer.toString(11, 16)); This takes the decimal value 11(not having a base at

How to convert a Binary String to a base 10 integer in Java

由 做~自己de王妃 提交于 2019-11-26 08:59:50
问题 I have an array of Strings that represent Binary numbers (without leading zeroes) that I want to convert to their corresponding base 10 numbers. Consider: binary 1011 becomes integer 11 binary 1001 becomes integer 9 binary 11 becomes integer 3 etc. What\'s the best way to proceed? I\'ve been exploring java.lang.number.* without finding a direct conversion method. Integer.parseInt(b) yields an integer EQUAL to the String...e.g., 1001 becomes 1,001 instead of 9...and does not seem to include a

How to convert an integer in any base to a string?

由 和自甴很熟 提交于 2019-11-25 22:32:32
问题 Python allows easy creation of an integer from a string of a given base via int(str, base). I want to perform the inverse: creation of a string from an integer , i.e. I want some function int2base(num, base) , such that: int(int2base(x, b), b) == x The function name/argument order is unimportant. For any number x and base b that int() will accept. This is an easy function to write: in fact it\'s easier than describing it in this question. However, I feel like I must be missing something. I
