Why should I not include cpp files and instead use a header?
... 1, that means you have to compile all two million lines again in order to test this. And if you find out that you meant to do a x = y - 1 instead, then again, two million lines of compile are waiting for you. That's many hours of time wasted that could be better spent doing anything else.

Determining complexity for recursive functions (Big O notation)
...us: T(n) = 1 + n - 1 which is exactly n or O(n).
Is the same as 1. You can test it your self and see that you get O(n).
T(n) = T(n/5) + 1 as before, the time for this method to finish equals to the time the same method but with n/5 which is why it is bounded to T(n/5). Let's find T(n/5) like in 1: T...
