PATHEADS - Patting Heads
It's Bessie's birthday and time for party games! Bessie has instructed the N (1 ≤ N ≤ 100,000) cows conveniently numbered 1..N to sit in a circle (so that cow i [except at the ends] sits next to cows i-1 and i+1; cow N sits next to cow 1). Meanwhile, Farmer John fills a barrel with one billion slips of paper, each containing some integer in the range 1..1,000,000.
Each cow i then draws a number Ai (1 ≤ Ai ≤ 1,000,000) (which is not necessarily unique, of course) from the giant barrel. Taking turns, each cow i then takes a walk around the circle and pats the heads of all other cows j such that her number Ai is exactly divisible by cow j's number Aj; she then sits again back in her original position.
The cows would like you to help them determine, for each cow, the number of other cows she should pat.
Input
- Line 1: A single integer: N.
- Lines 2..N+1: Line i+1 contains a single integer: Ai.
Output
- Lines 1..N: On line i, print a single integer that is the number of other cows patted by cow i.
Example
Input: 5 2 1 2 3 4 Output: 2 0 2 1 3
The first cow pats the second and third cows; the second cows pats no cows; etc.
