WebApr 6, 2024 · To determine the Big O runtime complexity we need to look at how many recursive calls are made. In this case there are two, and each of those recursive calls passes in n-1 as the new number disks. So a each call to the function doubles the number of recursive calls until n-1 is equal to 1. If N was equal to 4, N=4 -> 1 function call WebNov 6, 2014 · 17. There's a couple of different ways to solve recurrences: substitution, recurrence tree and master theorem.
