Write a method called threeHeads that repeatedly flips a coin until the results of the coin toss are three heads in a row. You should use a Random object to make it equally likely that a head or a tail will appear. Each time the coin is flipped, display H for heads or T for tails. When three heads in a row are flipped, the method should print a congratulatory message. Here is a possible output of a call to the method:

T T H T T T H T H T H H H
Three heads in a row!
