I know I may be asking too much on this one, but please hear me out. I'm taking a data management course in summer school, summer school is only 3 weeks long. So basically, I'm learn a large amount of material everyday for six hours, material that would normally take a semester(5 months) to cover. So, as you may imagine, the pacing of the course is very quick.
So please sympathize with situation. I really need help with this problem.
This is an organized counting problem.
