printing a pyramid of numbers separated by spaces

we were asked to have the following output as an example of wat is expected from this program, we were also advised to use nested for loops: pls help, a user can choose any number

1

121

12321

1234321

123454321

As luck would have it, I wrote a program about a year ago to print a pyramid on the console in response to a similar question on another forum. Here's the code:

using System;

class Program

{

static void Main()

{

Console.Clear();

Console.WriteLine("Enter 0 to quit at any time");

while (true)

{

Console.WriteLine();

Console.Write("Enter a number between 1 and 9 : ");

string reply = Console.ReadLine();

if (reply.Length == 1 && Char.IsDigit(reply[0]))

{

int number = int.Parse(reply);

if (number == 0) return;

Console.WriteLine();

int spaces = number - 1;

for(int i = 1; i <= number; i++)

{

if (spaces > 0)

{

Console.Write(new string(' ', spaces));

spaces--;

}

for(int j = 1 ; j <= i; j++)

{

Console.Write(j);

}

if (i > 1)

{

for(int k = i - 1; k >= 1; k--)

{

Console.Write(k);

}

Console.WriteLine();

}

else

{

Console.WriteLine("\n Not a valid number!");

}
