问题 I uploaded a txt file in to R as follows: Election_Parties <- readr::read_lines("Election_Parties.txt") Let's say the following text was in the file: P23-Andalusian Social Democratic Party (Partido Social-Demócrata Andaluz [PSDA]) P24-Andalusian Socialist Movement (Movimiento Socialista Andaluz [MSA]) P235-Andalusian Socialist Party-Andalucian Party (Partido Socialista Andalucista-Partido Andalucista [PSA-PA]) P26-Andalusist Party (Partido Andalucista [PA]) P217-Andecha Astur (Andecha Astur

问题 This question already has answers here : scanf() leaves the new line char in the buffer (4 answers) Closed 5 months ago . I'm the learning the very basics of C programming right now, and I'm practicing the scanf() function. This very, very simple program takes in a number and a letter and uses the printf() function to display the number and letter. If I ask the user to enter the number first, the program works, i.e., asks for a number, asks for a letter, and prints the input. If I ask for the

问题 I'm working on exam in which when the student asked to something like (declare if statement) he will answer in Rich text box. the question is: I want to search for the input of the student in that box, and therefore, I must declare a string that contains the code (as string) something like that: string check = " string stat = "new"; if (stat == "new") { Console.WriteLine(stat); } "; However, the problem is that, the escape characters and the other preserved voids such as (if). Briefly: I want

问题 So I have these giant XML files (and by giant, I mean like 1.5GB+) and they don't have CRLFs. I'm trying to run a diff-like program to find the differences between these files. Since I've yet to find a diff program that won't explode due to memory exhaustion, I've decided the best bet was to add CRLFs after closing tags. I wrote a python script to read char-by-char and add new-lines after '>'. The problem is I'm running this on a single core PC circa-1995 or something ridiculous, and it's

问题 I have the below ansible playbook where i am identifying a string in a file and replacing it with another --- - name: Ansible Playbook hosts: webserver1 remote_user: user45 tasks: - name: Replacing content with other lineinfile: path: /home/user45/run.sh regexp: '^(.*)DEBUG=(.*)$' line: 'DEBUG=ON' the above works, but it adds ^M to the end of every other line in that file and every blank line From what I have read online this normally occurs when you copy and paste from Windows to Linux but i

问题 How to sort characters in a string e.g. "5121" -> "1125" ? I can do this with code below but it seems too slow: var nonSortedString = "5121" var sortedString = String(Array(nonSortedString.characters).sort()) 回答1: The CharacterView handles properly compound characters and provides proper ordering ("eěf" vs. "efě"). If you are ok with the way C++ handles unicode characters, try using one of the other views, like nonSortedString.utf16.sort() . It should give speed similar to C++. 来源： https:/

问题 I need to display an output from a data record that is formatted similar to this: XXXX:12345 (Xxxxxxxxx) However, the only data I want to output is the "12345" and with two preceding zeros, i.e. the output should look like "0012345". The "12345" in the record is example only, each record has a unique number assigned. An example record looks like this: CAST:98765 (RPOS1234-XY) Can I use the ReplaceNoCase() to pull only that data out of the record? If so, how would I write the code to remove

问题 This is a question in the openDSA interactive learning platform from Virginia Tech: For function "countChr", write the missing part of the recursive call. This function should return the number of times that the letter "A" appears in string "str". int countChr(String str) { if (str.length() == 0) { return 0; } int count = 0; if (str.substring(0, 1).equals("A")) { count = 1; } return count + <<Missing a Recursive call>> } I know how to find a character non recursively in the following way:

问题 The task what I'm trying to do is about showing up the frequency of every single characters from the string object, for the moment I've done some part of code, just doesn't have the easy concept in my mind for finishing this task. So far I was thinking that it might be usefull to changing the char into int type. What is worth mentioning I'd like to avoid using the part: if (letter == 'a') NumberCount++; as if it wouldnt be efficient to write that much conditions for that simple task, and I
