These challenges will have a similar input format, which will come in on the Standard Input (STDIN). You need to print your solution to the Standard Output (STDOUT).

You will be provided with boilerplate code which processes the input into arrays and passed them to the method doStuff. To reload the boilerplate, you can click on "Reset Code" below.
