Using the given class definitions C++, create a minimum heap that stores integers and and implements a minimum priority queue. (Your program can be "hard coded" for integers - it does not need to use templates, generics, or polymorphism.)

Your data structure must always store its internal data as a heap.

Your toString function should return a string with the heap values as a comma separated list, also including the size of the heap as well. toString must show the values in the same ordering as they are in the array/heap.

Your heapsort function should create a new array with the sorted values and not modify(*) the heap. That resulting array must be sized to exactly hold the number of elements in the result. Since this is a minimum heap, the heap sort should generate data in descending order. (*): Note that "not modify" means that your data when the function terminates is the same as when you started, not necessarily that it wasn't changed at some time during execution of the function.

Your heapinsert function should return false if you try to insert values into a full heap (and return true on a sucessful insert.) minimum and extractMinimum should return 0 on an empty heap.

You are required to implement and use parent(i), left(i), and right(i) helper functions. I also recommend use of a "minimum of three" helper function as dscribed in class.

Don't forget a bounds checks as needed. (In general, make sure that all of your public functions are robust!)

For this assingment, please create a zero-based heap (where A[0] is the root) as described in class, and not a one-based heap (where A[1] is the root) as described in the textbook.

You may make minor adjustments to the class definitions (for example, adding extra helper functions or overloading the constructor to accept initial values,) but any major changes must have prior approval in writing (do this via email.)
