Solution 1

Surely a homework!

It's a recursive method that probably is doing sum of natural numbers. Following should be ok:

C#

public int sum(int n)
{
     if(n==1)
        return 1;

     int s;
     s = n + sum(n-1);
     return s ;
}

Solution 2

The most common cause of stack overflow is excessively deep or infinite recursion.So you need to terminate with some condition.
