     * Return a version of the given array where all the 10's have been removed.

     * and the empty spaces a the end of the array should be 0.
     * So {1, 10, 10, 2} yields {1, 2, 0, 0}.
     * You may modify and return the given array or make a new array.

     * My personal solution was not so successfull, so I started to look up for other solutions online
     * and found one here: http://gregorulm.com/codingbat-java-array-2-part-iii/
     * Yes, I copied itm but i thoroughly studied it to benefit in future.
