## C# Sharp Recursion: Exercise-2 with Solution

Write a program in C# Sharp to print numbers from n to 1 using recursion.

Sample Solution:-

C# Sharp Code:

``````using System;

class RecExercise1
{
static int printNatural(int ctr,int stval)
{
if (ctr < 1)
{
return stval;
}

Console.Write(" {0} ",ctr);
ctr--;
return printNatural(ctr,stval);
}

static void Main()
{
Console.Write("\n\n Recursion : Print the natural numbers from n to 1 :\n");
Console.Write("--------------------------------------------------------\n");
Console.Write(" How many numbers to print : ");
// Call recursive method with two parameters.
printNatural(ctr,1);
Console.Write("\n\n");
}
}
```
```

Sample Output:

```Recursion : Print the natural numbers from n to 1 :
--------------------------------------------------------
How many numbers to print : 20
20  19  18  17  16  15  14  13  12  11  10  9  8  7  6  5  4  3  2  1
```
