PRINT A PALINDROME WITH NUMBERS AND STARS APPROACH The same flag can be set to 0 and 1 simultaneously to print * and the Ith iteration number continuously inside the triangle. The same logic used in the previous problem is used here to create a triangle pattern.

                             PRINT A NUMBER PYRAMID AS MENTIONED BELOW : APPROACH The whole pyramid structure can be written in a single nested for loop instead of many separate loops A single nested for loop is used along with two flags that help in creating the pyramid structure.One flag moves towards left by 1 and the other to the right by 1. If the iteration is at the boundary of the triangle ( leftTriangleCreater, rightTriangleCreater)  , those can print the Ith Iteration value While loop can be used to control the values on the left and right. In the left , The while loop iterates till secondelement != middleNumber In the right, The while loop iterates till rightsecondElement > i SOLUTION using System; public class Test { public static void Main() {   var number = Console.ReadLine();   int n = Convert.ToInt32(number);   Pattern print = new Pattern();   print.NumberPyramid(n); } } public class Pattern { public vo
