Write a method named swapPairs that accepts an array of strings as a parameter and switches the order of values in a pairwise fashion. Your method should switch the order
of the first two values, then switch the order of the next two, switch the order of the next
two, and so on. For example, if the array initially stores these values:
String[] a = {"four", "score", "and", "seven", "years", "ago"};
swapPairs(a);
Your method should switch the first pair ("four", "score"), the second pair ("and", "seven") and
the third pair ("years", "ago"), to yield this array:
{"score", "four", "seven", "and", "ago", "years"}
If there are an odd number of values, the final element is not moved. For example, if the
original list had been:
{"to", "be", "or", "not", "to", "be", "hamlet"}
It would again switch pairs of values, but the final value ("hamlet") would not be moved,
yielding this list:
{"be", "to", "not", "or", "be", "to", "hamlet"}
