Kirat[ad_1] Let’s assume your input file contains the following as in your example: 1 + 2 + 5 – 3 = The outer scanf reads with %d. This picks up 1 as the integer value 1 and puts it in result. Now the inner scanf runs with %c. It reads the space after 1 so … Read more
[ad_1] An optimal solution for this would have you traverse the entire list of volumes only once, or O(n). The loops you mentioned were doing some multiple of that. There may be a way to do this with Linq to attain O(n) efficiency, but without more testing I do not know. However, you can get … Read more
[ad_1] Without seeing the data, lets make some assumptions: A pass is awarded for a subject if the marks obtained for that subject are equal to or more than 50% of the total marks available for that subject.

[ad_1] Try below function static void sort(Map<String, List<String>> stringListHashMap) { stringListHashMap.forEach((key, value) -> { Collections.sort(value); }); } [ad_2] solved sort hashmap value of type list using java 8 [duplicate]
[ad_1] It is minimal example which create database with two elements and later it uses data from database to fill Treeview You have to use create() only once. import tkinter as tk from tkinter import ttk import sqlite3 def create(con): cur = con.cursor() cur.execute(”’CREATE TABLE IF NOT EXISTS user ( id INTEGER PRIMARY KEY, name … Read more
[ad_1] You can use sympy, Python’s symbolic math library. from sympy import solve from sympy.abc import C print(solve(1298 + 74.86 * C + 1.283 * C ** 2 – .0078 * C ** 3 – .0006 * C ** 4)) # result: [-28.2719434096994, 62.3383358961427, -23.5331962432216 – 25.9550273611766*I, -23.5331962432216 + 25.9550273611766*I] 0 [ad_2] solved How to … Read more
[ad_1] ckeditor(text)+ckfinder(image) Or you can use Summernote with server side image upload setup $(‘#Editor’).summernote({ lang: ‘fa-IR’, callbacks: { onImageUpload: function (files) { var $editor = $(this); var data = new FormData(); data.append(‘imageFile’, files[0]); $.ajax({ url: ‘/Server/UploadImage’, method: ‘POST’, data: data, processData: false, contentType: false, success: function (url) { $editor.summernote(‘insertImage’, url); } }); } } }); … Read more
[ad_1] Suppose the old repository url is https://gitlab.com/foo/oldbar.git and the new one is https://gitlab.com/foo/newbar.git. cd local_repo git remote set-url origin https://gitlab.com/foo/newbar.git git push origin refs/remotes/origin/*:refs/heads/* refs/tags/*:refs/tags/* In case you have unpushed commits on master, git pull origin -r master git push origin -u master [ad_2] solved How can I push all branches and tags to … Read more
[ad_1] This seems like a regular expression. There * is not a wildcard but a quantifier. It means that the preceding character or group can occur zero or more times. . is a wildcard. It means any character except newline. […] is a character set. It means any character from the set. . is a … Read more
[ad_1] i solved it: number_of_laptops = int(input()) list_of_prices = [] list_of_qualities = [] for i in range(0,number_of_laptops): inp = input() numbers = [] numbers = [int(s) for s in inp.split() if s.isdigit()] list_of_prices.append(numbers[0]) list_of_qualities.append(numbers[1]) def find_better_lp(number_of_laptops): if number_of_laptops == 0: return print(“empty list”) for i in range(0,number_of_laptops): for j in range(0,number_of_laptops): if((list_of_prices[i] <= list_of_prices[j]) and … Read more
[ad_1] Question: “I should take textfield value from the cell. how can I do that?” Answer: You shouldn’t do that. View objects are for displaying information to the user and for collecting input, not for storing data. This is especially important for UICollectionViews and UITableViews, since both of those create and recycle cells as needed … Read more
[ad_1] { x = a; y = b; } is the compound statement of the constructor point( int a = 0, int b = 0 ); Maybe it will be more clear if to rewrite the constructor like point( int a = 0, int b = 0 ) { x = a; y = b; … Read more
[ad_1] I want to know what is purpose of new URLClassLoader(new URL[0],getClass().getClassLoader()); It means: make a new URLClassloader that loads classes / resources from an empty array of URLs, and has this classes classloader as the parent. The resulting classloader object is then discarded. So I think this is just testing to see if the … Read more
[ad_1] var count_br = “4,7,10”; var count_ = count_br.split(“,”); var i; for (i = 0; i < count_.length; ++i) { for(let idx in count_) count_[idx] = (parseInt(count_[idx])+4).toString() } console.log(count_) [ad_2] solved Increment all values of [closed]
[ad_1] Not really sure how you want to add them, as int’s or Strings, but remember they have to be Objects. class Inp { public void scan() { Scanner sc = new Scanner(System.in); HashMap<Integer,Integer> map = new HashMap<Integer,Integer>(); while (true) { String sr = sc.nextLine(); String[] tk = sr.split(” “); Integer key = 0, value … Read more
