මාත challenge එක කරා හැබැයි python වලින් නම් නෙවෙයි 😊 import java.util.ArrayList; import java.util.Scanner; public class Main { public int inputNumber; public ArrayList list = new ArrayList(); public static void main(String[] args) { Main obj = new Main(); Scanner sc = new Scanner(System.in); System.out.print("Enter number : "); obj.inputNumber = sc.nextInt(); for (int i = 0; i < obj.inputNumber; i++) { int ans = obj.getTriangular(i); obj.list.add(ans); } System.out.print("Triangular numbers are : "); for (int i = 0; i < obj.list.size(); i++) { if ( i == (obj.list.size() - 1) ){ System.out.println( obj.list.get(i)); }else{ System.out.print( obj.list.get(i)+" , "); } } int size = obj.list.size() - 1; System.out.print("Enter number between 0 and "+size+" : "); int inputSize = sc.nextInt(); if ( size >= inputSize){ System.out.println("The Triangular number at index "+inputSize+" is " + obj.list.get(inputSize)); }else{ System.out.println("Invalid number"); } } public int getTriangular(int x) { return x * (x + 1) / 2; } }

Sample answer for fun :) entered_number = int(input("Enter a number: ")) answers = [((i * (i + 1)) // 2) for i in range(1,entered_number) if ((i * (i + 1)) // 2) < entered_number] #print the list print(f"Triangular numbers up to {entered_number} : {answers}") #print the answer for entered index prompt = int(input(f"Enter a number between 0 to {int(len(answers))-1}: ")) print(f"The Triangular number as index {str(prompt)} is: {answers[prompt]}")
