using System;
class Test
{
       public static void Main()
       {
              int i,j;
              int[,] a=new int[5,5];
              Console.WriteLine();              for(i=0;i<5;i++)
              {
            a[i,0]=1;
                     a[i,i]=1;
              }              for(i=2;i<5;i++)
                     for(j=1;j<i;j++)
                            a[i,j]=a[i-1,j-1]+a[i-1,j];
              for(i=0;i<5;i++)
              {
                     for(j=0;j<=i;j++)
                            Console.Write("{0}",a[i,j]);
                     Console.WriteLine();
              }              Console.ReadLine();       }}
