Determining complexity for recursive functions (Big O notation)
...lp you understand how to calculate any method.
I recommend reading it from top to bottom to fully understand how to do it:
T(n) = T(n-1) + 1 It means that the time it takes for the method to finish is equal to the same method but with n-1 which is T(n-1) and we now add + 1 because it's the time it...
