Write a method called printLevel that takes an integer n as a parameter and that prints the values at level n from left to right. The values should be printed one per line. By definition, the overall root is at level 1, it's children are at level 2, and so on. For example, if a variable t stores a reference to the following tree: (12(19,11,14),(93,empty,15)) then the call: t.printLevel(3); would produce the output: 11 14 15
