Determining complexity for recursive functions (Big O notation)
...ant.
5.
T(n) = n / 2 + T(n - 5)
where n is some constant
Rewrite n = 5q + r where q and r are integer and r = 0, 1, 2, 3, 4
T(5q + r) = (5q + r) / 2 + T(5 * (q - 1) + r)
We have q = (n - r) / 5, and since r < 5, we can consider it a constant, so q = O(n)
By induction:
T(n) = T(5q + r)
