In this section we discussed recursive implementation of getOndexOf method. Please explain how this implementation satisfies 4 principles of recursive techniques and discuss if this implementation is better or iterative one? template int ArrayBag::getIndexOf(const ItemType& target, int searchIndex) const { int result = -1;

if (searchIndex < itemCount)

{

if (items[searchIndex] == target)

{

result = searchIndex;

}

else {

result = getIndexOf(target, searchIndex + 1);

} // end if

} // end if return result; } // end getIndexOf
