Java

C#

using System;

class PatternProg
{
  public static void Main()
  {
    int n = 5;


    int x = 1, k;

    for (int i = 1; i <= n; i++)
    {
      k = x + i;
      for (int j = 1; j <= i; j++)
      {
        if (i % 2 == 1)
        {
          Console.Write("{0,2:D} ", (x + j - 1));
        }
        else
        {
          Console.Write("{0,2:D} ", (k - j));
        }

        if (j != i)
        {
          Console.Write("# ");
        }
      }
      x = x + i;
      Console.WriteLine();
    }

    Console.ReadKey(true);
  }
}

Python

n = 5

d = 1

for x in range(1, n + 1):
  k = d + x
  for y in range(1, x + 1):
      if x % 2 == 1:
         print("{:2d} ".format(d + y - 1), end="")
      else:
         print("{:2d} ".format(k - y), end="")

      if y != x:
         print("# ", end="")

  d = d + x
  print()
