Something along these lines should work. I might have made syntax errors 😀 using System; class Program { static void Main(string[] args) { var calculator = new Calculator(); var input = GetNumbers(); calculator.Add(input); Console.WriteLine(calculator.Add(input)); } public static int[] GetNumbers() { Console.WriteLine(“Enter Numbers Seperated With a Space”); string input = Console.ReadLine(); //Get user input with this … Read more
If you want to add all the values of s1, you need to iterate over the values() of dictionary students. students={ 1: {“pup1”: “001”, “s1”: 10, “s2”: 20}, 2: {“pup2”: “124”, “s1”: 20, “s2”: 30}, 3: {“pup3”: “125”, “s1”: 30, “s2”: 40}} sum1 = 0 for data in students.values(): sum1 += data[‘s1’] avg = sum1 … Read more
Run this code and test with all your inputs.It should solve your scenario. String regex = “^[0-9.]{5}$”; Pattern pattern = Pattern.compile(regex); String name= “123.4”; Matcher matcher = pattern.matcher(name); System.out.println(matcher.matches()); 1 solved Regex for string that validates for a number which may include decimal and for a particular length [closed]

The really smart answer is: #include <algorithm> As in: #include <iostream> #include <algorithm> main() { int x = 1, y = 2; std::swap <int> (x, y); std::cout << “Expecting 2: ” << x << std::endl; std::cout << “Expecting 1: ” << y << std::endl; } Because swap is already included in <algorithm>! The best C++ … Read more
You never alter self.n, so it’ll always be greater or equal to 1. You created an endless loop. It’s set to 1 in __init__ so self.n >= 1 is true each time you test. You should not use a local variable and a parameter to track the current state of the factorial function. Pick one … Read more
