     * Let assume that the program is invoked with the following
     * line:
     *  java IntroductionExercises 0 3 4 5
     *
     * The arguments of the program are 0, 3, 4 and 5.
     * After the execution of the main, the variable squares
     * should be:
     *  squares = [0, 9, 16, 25]
     *
     * If an exception occurs when converting an argument to
     * an integer, put 0 at the corresponding index. For example
     *
     *  java IntroductionExercise 0 3.1 4 5
     *
     * would yield
     *
     *  squares = [0, 0, 16, 25]
     *
     * because 3.1 can not be converted to an integer
