HW #1

It took me a while to figure out a way to exit out of the program immediately when the user inputs a correct number. I first used return 0, but it gave me error: "ruby localjumperror unexpected return". Then I figured it out searching on google and used the "exit" method instead. Also I wasn't sure how often I should comment on our code. Is it appropriate to comment on each if statement?

Regarding the git I tried to fix the comments on commit and uncommited everything and lost the changes accidently using the following command. (git reset --hard HEAD^).
```ruby
if x == random_num
    puts "Congratulations! You guessed the right number!"
    exit
else
    puts "The number is #{ (x < random_num) ? "lower" : "higher" } than your guess."
end
