Try:

C#

Console.WriteLine("1");
Console.WriteLine("1 2 1");
Console.WriteLine("1 2 3 2 1");
Console.WriteLine("1 2 3 4 3 2 1");
Console.WriteLine("1 2 3 4 5 4 3 2 1");

If you mean "Please write the code to do this dynamically so I get a job I don't deserve and can't do", then I really think you should write it yourself, as if you can't I for one do not want to work next to you!

Solution 1

A for loop[^] along with string concatenation[^] should act as a hint for you to proceed further.

You do need three loops (or two and an insert as well as a concatenation) to do the "up then down".
But it's, what? Six lines of C# plus curly brackets if you do it with Console.Write?
If he can't do that...:sigh:
