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...
