Don't understand about Recursive Method

[SexyFlip]

I don't understand this example at all.. how can i ask user for input and then check for the size?

Code: Select all

   public int mystery(int a[], int size)
   {
   
   if ( size==1)
   return a[0];

   else
   return a[size-1] + mystery(a,size-1);
   }
}

size variable is not represent the size of array , it is number of elements in array a[] which user wants to add.
This function will addition of first three elements if i call the above method like mystery(a,3);
