word-count

问题 I am trying to implement a programme that counts the words in a multiline textbox as you type. I can get it counting the words until I press the "enter" key and type a word. It does not recognise this. This is my code: Private Sub TextBox1_TextChanged(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles TextBox1.TextChanged Dim str As String Dim i, l, words As Integer str = TextBox1.Text str = LTrim(str) 'removes blank spaces at the beginning of text str = RTrim(str) '

问题 I was looking for a Disk intensive Hadoop application to test the I/O activity in Hadoop but I couldn't find any such application which kept the Disk utilization above, say 50% or some such application which actually keeps disk busy. I tried randomwriter, but that surprisingly is not disk I/o intensive. So, I wrote a tiny program to create a file in Mapper and write some text into it. This application works well, but the utilization is high only in the master node which is also name node, job

问题 After trying to figure how to have an effective word counter of a string, I know about the existing function that PHP has str_word_count but unfortunately it doesn't do what I need it to do because I will need to count the number of words that includes English, Chinese, Japanese and other accented characters. However str_word_count fails to count the number of words unless you add the characters in the third argument but this is insane , it could mean I have to add every single character in

问题 I am a beginner in hadoop using the hadoop's beginners guide book as a tutorial. I am using a mac osx 10.9.2 and hadoop version 1.2.1 I have set all the appropriate class path, when I call echo $PATH in terminal: Here is the result I get: /Library/Frameworks/Python.framework/Versions/2.7/bin:/Users/oladotunopasina/hadoop-1.2.1/hadoop-core-1.2.1.jar:/Users/oladotunopasina/hadoop-1.2.1/bin:/usr/share/grails/bin:/usr/share/groovy/bin:/Users/oladotunopasina/.rvm/gems/ruby-2.1.1/bin:/Users

问题 I am trying to get a phrase count from a text file but so far I am only able to obtain a word count (see below). I need to extend this logic to count the number of times a two-word phrase appears in the text file. Phrases can be defined/grouped by using logic from NLTK from my understanding. I believe the collections function is what I need to obtain the desired result, but I'm not sure how to go about implementing it from reading the NLTK documentation. Any tips/help would be greatly

问题 I am trying to run word count example on Eclipse . Generally when we click on "run on hadoop" option in eclipse we get a new window asking to select server location. But, now it is directly running the program without asking me to choose an existing server from list below. I think because of this I am getting the following exception: 13/04/21 08:46:31 ERROR security.UserGroupInformation: PriviledgedActionException as:hduser1 cause:org.apache.hadoop.mapred.InvalidInputException: Input path

问题 I have a few text files and I'd like to count how many times a letter appears in each? Specifically, I'd like to use the UNIX shell to do this, in the form of: cat file | .... do stuff... Is there a way I can get the wc command to do this? 回答1: grep char -o filename | wc -l 回答2: Another alternative: tr -d -C X <infile | wc -c where X is the character or string of characters you want to count and infile is the input file. 回答3: Alternative to grep: sed 's/[^x]//g' filename | tr -d '\012' | wc

问题 I need to create a program that shows a sentence with the most words in it. string [] st = { "I like apples.", "I like red apples.", "I like red apples than green apples." }; foreach (string s in st) { int NumberOfWords = s.Split(' ').Length; } The result should be displaying "I like red apples than green apples". 回答1: Probably, you have the sentences in different TextBox control in your Form. For you to know which sentence have more words in it; split the sentence by space and get a count of
