Overview

The Mechanic Scheduler manages a list representing disjointed intervals of integers.

Example

$ ruby run.rb 
Hi, What is your name? 
John

Hi, John!
I can manage intervals for integer numbers. I can add or remove intervals through methods.

What command do you want? e.g: add(1,5) or remove(2,3) (call 'exit' to exit).
add(1,5)
Interval [1, 5] added successfully!
>> [[1, 5]]
What command do you want? e.g: add(1,5) or remove(2,3) (call 'exit' to exit).
remove(2,3)
Interval [2, 3] removed successfully!
>> [[1, 2], [3, 5]]
What command do you want? e.g: add(1,5) or remove(2,3) (call 'exit' to exit).
add(6,8)
Interval [6, 8] added successfully!
>> [[1, 2], [3, 5], [6, 8]]
What command do you want? e.g: add(1,5) or remove(2,3) (call 'exit' to exit).
remove(4,7)
Interval [4, 7] removed successfully!
>> [[1, 2], [3, 4], [7, 8]]
What command do you want? e.g: add(1,5) or remove(2,3) (call 'exit' to exit).
add(2,7)
Interval [2, 7] added successfully!
>> [[1, 8]]
What command do you want? e.g: add(1,5) or remove(2,3) (call 'exit' to exit).
exit
Okay, cya!
