/*A class called Pair has already been declared, but the constructors have not been implemented yet. Pair has two public member variables:

        int *pa,*pb;

These two "pointers to int" are intended to point to heap memory locations that store integers. The remainder of the Pair class expects the following functionality.

A single constructor Pair(int a, int b): This should set up pa and pb to point to newly allocated memory locations on the heap. The integers at those memory locations should be assigned values according to the constructor's integer arguments a and b.

A copy constructor Pair(const Pair& other): This takes as its argument a read-only reference to another Pair. It should set up the newly constructed Pair as a "deep copy," that is, it should create a new Pair that is equivalent to the other Pair based on dereferenced values but does not reuse any of the same memory locations. In other words, the copy constructor should set up its own instance's member variables pa and pb to point to newly a
