What would be wrong with modifying the UnsortedType class as follows?

private: ItemType * info; // CHANGE: make the array a pointer int length; // rest of fields are unchanged from the current version of the code public: UnsortedType(ItemType *vals, int lgth) { // CHANGE: pass in array info = vals; length = lgth; } // leave rest alone 

	a.	The constructor should allocate a new array and copy the elements of the parameter into this new array
	b.	The new version of UnsortedType is fine
	c.	the array parameter to the constructor might have fewer than 5 elements
	d.	info should still be an array instead of a pointer

	b.	O(2A*D*E)
	c.	O(A+D+E)
	d.	O(A*D*E)
