In the fifth episode of Idiomatic Kotlin’s #AdventOfCode series, we'll look at a “hidden” binary encoding for natural numbers that can be used to identify seats on a plane, along with the Kotlin solution for the challenge. Along the way, we'll discuss the Kotlin standard library functions for working with the binary representation of numbers, the power of local functions, and why ‘max’ disappeared from the standard library but will “reappear” in a new form.
