/* Author: LukArToDo Created: 20.april 2018 Bugs: unknown (20.april 2018 : bug was found by Nevfy - see comment section. It is corrected now 😉) Description: The code finds gravity of randomly numbers according to the next rules: (<<) = Mass to left is greater. (>>) = Mass to Right is greater. (><) = Mass is equal both sides. (0) = Blackhole all surrounding mass gravitates towards this.
