words

问题 I'm helpless on regular expressions so please help me on this problem. Basically I am downloading web pages and rss feeds and want to strip everything except plain words. No periods, commas, if, ands, and buts. Literally I have a list of the most common words used in English and I also want to strip those too but I think I know how to do that and don't need a regular expression because it would be really way to long. How do I strip everything from a chunk of text except words that are

问题 As part of my course, I have to learn C using Turbo C (unfortunately). Our teacher asked us to make a piece of code that counts the number of characters, words and sentences in a paragraph (only using printf, getch() and a while loop.. he doesn't want us to use any other commands yet). Here is the code I wrote: #include <stdio.h> #include <conio.h> void main(void) { clrscr(); int count = 0; int words = 0; int sentences = 0; char ch; while ((ch = getch()) != '\n') { printf("%c", ch); while (

问题 I'm trying to make a regular expression that accepts this: Only a-z, 0-9, _ chars, with a minimum length of 3 admin, static, my and www are rejected. For the first part, I already managed to do it with : ^[a-zA-Z0-9\\_]{3,}$ But I don't know how to exclude the words listed previously. For example, that would mean : static is not allowed (of course), but statice is allowed estatic is allowed Using this regular expression : ^(?!static|my|admin|www).*$ doesn't work well : it excludes statice

问题 I have documents in Solr/Lucene (3.x) with a special copy field facet_headline in order to have an unstemmed field for faceting. Sometimes 2 ore more words are belong together, and this should be handled/counted as one word, for example "kim jong il". So the headline "Saturday: kim jong il had died" should be split into: Saturday kim jong il had died For this reason I decided to use protected words (protwords), where I add kim jong il . The schema.xml looks like this. <fieldType name="facet

问题 I wrote up a program that can sort words and determine any anagrams. I want to generate an array of random strings so that I can test my method's runtime. public static String[] generateRandomWords(int numberOfWords){ String[] randomStrings = new String[numberOfWords]; Random random = Random(); return null; } (method stub) I just want lowercase words of length 1-10. I read something about generating random numbers, then casting to char or something, but I didn't totally understand. If someone

问题 Let's say I have a column family named Questions like below: Questions = { Who are you: { username: "user1" }, What is the answer: { username: "user1" }... } How do I search for all the questions that contain certain words? Get all questions that contain 'what' word. How do I do it using python or at least Java? 回答1: Solandra (https://github.com/tjake/Solandra) is the new name for Lucandra. Solandra is a combination of Cassandra and Solr (which is based on the Lucene full-text search engine).

问题 I'm in the early stages of designing a series of simple word games which I hope will help me learn new words. A crucial part of the ideas that I have is a fully parsable dictionary; I want to be able to use regular expressions to search the dictionary for given words and extract certain other bits of information (e.g. definition, type (noun/verb...), synonyms, antonyms, quotes demonstrating the word in use, etc). I currently have Wordbook (mac app) which I find okay, but haven't figured out

问题 I'm working on a program that converts numbers to words, but I'm having problems with the toString() method in the Numbers class. All the methods were given to me, so I could implement; therefore, I can't remove any of them... number: 4564 --> four thousand and five hundred and sixty four here's the code Numbers class package numberstowords; import java.util.*; public class Numbers { //array containing single digits words numbers:0-9 private final String[] SINGLE_DIGITS_WORDS; //array

问题 I am trying to break a large string of text into several smaller strings of text and define each smaller text strings max length to be different. for example: "The quick brown fox jumped over the red fence. The blue dog dug under the fence." I would like to have code that can split this into smaller lines and have the first line have a max of 5 characters, the second line have a max of 11, and rest have a max of 20, resulting in this: Line 1: The Line 2: quick brown Line 3: fox jumped over

问题 This question already has answers here : Letter Count on a string (11 answers) Closed 2 years ago . I am trying to make a Python script which counts the amount of letters in a randomly chosen word for my Hangman game. I already looked around on the web, but most thing I could find was count specific letters in a word. After more looking around I ended up with this, which does not work for some reason. If someone could point out the errors, that'd be greatly appreciated. wordList = ["Tree",
