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?
x ≤ 109, q ≤ 105.
