I have some difficulty trying to tell which equation to use when I'm given an explanation on how an algorithm operates. Especially divide and conquer.
Normally I see these kind of equations:
C(n) = aC(n/a) + b where a and b are constants
Other times I don't see the a in front of C(n/a) as an answer. That really confuses me.
Can you tell me when I will need to use which?
