Write a class template named SortableVector. The class should be derived from the SimpleVector class presented in this chapter. It should have a member function that sorts the array elements in ascending order. (Use the sorting algorithm of your choice). Test the template in a driver program that will encompass a basic built in data type (such as int, float, or string) and the Fractions class we have done (use the most recent version of the Fractions class from 5/11/20 meeting for better results).

Write a method replacekey in the minheap class with the following signature: public void replacekey(integer oldkey, integer newkey) the method will replace the first occurrence of oldkey with the newkey, and restore the min-heap property after the change. if the oldkey does not exist in the heap, the method prints an appropriate message and returns without changing the heap. example: suppose our binary heap object (bh) has the following keys: *** 4 6 7 32 19 64 26 99 42 54 28 then the method call: bh.replacekey (oldkey integer(54), newkey integer(2))
