Your backpack contains \(2010\) chocolate bars, which you are going to divide between your best friend and yourself. You think you are a nice person, so you will give your best friend more than zero chocolate bars. However, you have been craving chocolate recently, and so you must have at least twice as many chocolate bars as your friend after you finish dividing them. What is the difference between the maximum and minimum number of chocolate bars you can have?
