Determining complexity for recursive functions (Big O notation)
...) = a + 2 * T(n - 1)
where a is some constant
By induction:
T(n) = a + 2a + 4a + ... + 2^(n-1) * a + T(0) * 2^n
= a * 2^n - a + b * 2^n
= (a + b) * 2^n - a
= O(2 ^ n)
where a, b are some constant.

T(n) = n / 2 + T(n - 5)
where n is some constant
Rewrite n = 5q + r where...

... merging master onto topic
D: 37ad159 post-branch commit on master
C: 132ee2a first commit on topic branch
B: 6aafd7f second commit on master before branching
A: 4112403 initial commit on master
So, the goal: find B. Here are three ways that I found, after a bit of tinkering:
