write a program to print Pascal Triangle

For example:

Input:
3

Output:
1
1	1
1	2	1

Solution:

using System;

namespace PascalTraingle
{
    class Program
    {
        public static void Main()
        {
            Console.WriteLine("Enter a number:");
            var rows = Convert.ToInt32(Console.ReadLine());

            for (var i = 0; i < rows; i++)
            {
                var val = 1;
                for (var j = 0; j <= i; j++)
                {
                    Console.Write(val + " ");
                    val = val * (i - j) / (j + 1);
                }
                Console.WriteLine();
            }
            Console.ReadLine();
        }
    }
}
