Question

I want to make a function which will display numbers starting from 1 to 100 and 100 to 1
I am confused that how i can do this using Recursion?

I dont want to do this using any other loop.
Please provide me hint and ignore my way of asking because i am new in c++ and c#.

Answer 1

void Print100(int n)
{
   if (n > 100)
   {
       Console.WriteLine();  // cosmetic
       return;               // stop recursing
   }

   Console.WriteLine(n);     // 1-100
   Print100(n+1);            // recurse
   Console.WriteLine(n);     // 100-1, on the way out
}


void Main()
{
    Print100(1);
}
