Implementation of Yang Hui triangle in C #

Problem Description: Create a program to find triangles. The program prompts the user to enter data and then shows the law of the Yang Hui Triangle.

Input Description: Yang Hui triangle length, representing the value

Program output: Yang Hui triangle

using system;using system.collections.generic;using system.linq;using System.Text;       Namespace consoleapplication2{class Program {static void Main (string[] args) {int length = 0;//Yang Hui triangle      Console.Write ("Input yang hui triangle length:");  Length = Convert.ToInt32 (Console.ReadLine ());//Specifies the Yang Hui of the triangle int[][] A = new int[length][];//two-dimensional array for (int i = 0; i < A.length; i++) A[i] = new Int[i + 1];//traversal, assignment increment for (int j = 0; J < A.length; J + +) {a[j][0] = 1;//Put 1th column of the meta Vegetarian 1 A[j][j] = 1; Assign 1 for (int m = 1; m < a[j] to the rightmost element of each of the 1 columns. Length-1; m++) A[j][m] = A[j-1][m-1] + a[j-1][m];//The value of the remaining elements is calculated by the Yang Hui formula} for (int i = 0; i < a.length; i++)// Iterate through the array output Yang Hui triangle {for (int j = 0; J < A[i].
