[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.

题目大意

今天是贝茜的生日,为了庆祝自己的生日,贝茜邀你来玩一个游戏。

贝茜让 NN (1N1051\leq N\leq 10^5) 头奶牛坐成一个圈。除了 11 号与 NN 号奶牛外,ii 号奶牛与 i1i-1 号和 i+1i+1 号奶牛相邻。NN 号奶牛与 11 号奶牛相邻。农夫约翰用很多纸条装满了一个桶,每一张包含了一个不一定是独一无二的 1110610^6 的数字。

接着每一头奶牛 ii 从柄中取出一张纸条 AiA_i。每头奶牛轮流走上一圈,同时拍打所有手上数字能整除在自己纸条上的数字的牛的头,然后做回到原来的位置。牛们希望你帮助他们确定,每一头奶牛需要拍打的牛。
