[USACO08DEC] Patting Heads S
题目描述
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 A_i (1 <= A_i <= 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 A_i is exactly
divisible by cow j's number A_j; 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.
输入格式
* Line 1: A single integer: N
* Lines 2..N+1: Line i+1 contains a single integer: A_i
输出格式
* Lines 1..N: On line i, print a single integer that is the number of other cows patted by cow i.
