Less Than 2015 (Posted on 2015-09-22) Difficulty: 3 of 5
The function f is defined on the positive integers as follows:
  1. f(1) = 1, and:
  2. f(2n) = f(n), if n is even, and:
  3. f(2n) = 2*f(n), if n is odd, and:
  4. f(2n + 1) = 2*f(n) + 1, if n is even, and:
  5. f(2n + 1) = f(n), if n is odd, and:
Determine the number of positive integers n which are less than 2015 and have the property that f(n) = f(2015).
