Find count of integers x such that x or y = x

Revision en2, by f2lk6wf90d, 2017-10-17 15:06:29

Hello everyone, I thought of this problem after reading 875D - High Cry and I can't figure out a solution.
Let's call an integer y a subset of an integer x, if x | y == x.

You have to answer q queries of two types:

• 1 x Add the integer x to the set S. (initially, the set S is empty)
• 2 x Of all the integers currently in S, how many is x a subset of?

1 ≤ x ≤ 109, 1 ≤ q ≤ 105.
