Swap the Values in a Generic Pair

Complete the swap() method in the Pair<T> class so it exchanges the values of first and second.

The full class is provided. Only fill in the body of swap().

IMPORTANT: Do NOT write a main method. A hidden test will create String and Integer pairs, call swap(), then print the swapped values using getFirst() and getSecond().
