Question

This method uses recursion to find the area of a triangle with a given width.

public int getArea()
{
    if (width == 1)
    {
        return 1;
    }
    else
    {
        Triangle smallerTriangle = new Triangle(width - 1);
        int smallerArea = smallerTriangle.getArea();
        return smallerArea + width;
    }

Using this example, outline, but do not implement, a recursive solution for finding the smallest value in an array.  For example, suppose we have an Integer array with elements [12, 15, 28, 32, 3, 7, 21].  Outline how we can use recursion to find the smallest element, 3, in the array.
