The repository is initially using defined?() method in ruby to tell me if an assignment occoured. Assignment will print adjacently, but print max 1 newline for any number of non assignments between previous assignment and non assignment.

output intended:

it should print line number, var name, and var value line 10, testB, val 5 || line 11, testB, val 4 || line 10, testB, val 6 || line 11, testB, val 4

line 20, testC, val 2 || line 21, testD, val 3

line 24, testB, val 2

end
