- in one terminal run "java Main", if it returns "false" there's a bug
- in another you can bisect by typing: "git bisect start" "git bisect bad head" "git bisect good <some commit you checked out with "git log --oneline" and "git checkout " from the past where program returns "true"> to avoid searching for one you can use the commit hash "4a517f3" so: "git bisect good 4a517f3"
