Description

Vasya has been playing Plane of Tanks with his friends the whole year. Now it is time to divide the participants into several categories depending on their results.

A player is given a non-negative integer number of points in each round of the Plane of Tanks. Vasya wrote results for each round of the last year. He has n records in total.

In order to determine a player's category consider the best result obtained by the player and the best results of other players. The player belongs to category:

"noob" — if more than 50% of players have better results;

"random" — if his result is not worse than the result that 50% of players have, but more than 20% of players have better results;

"average" — if his result is not worse than the result that 80% of players have, but more than 10% of players have better results;

"hardcore" — if his result is not worse than the result that 90% of players have, but more than 1% of players have better results;

"pro" — if his result is not worse than the result that 99% of players have.

When the percentage is calculated the player himself is taken into account. That means that if two players played the game and the first one gained 100 points and the second one 1000 points, then the first player's result is not worse than the result that 50% of players have, and the second one is not worse than the result that 100% of players have.

Vasya gave you the last year Plane of Tanks results. Help Vasya determine each player's category.

Input

The first line contains the only integer number n (1 ≤ n ≤ 1000) — a number of records with the players' results.

Each of the next n lines contains a player's name and the amount of points, obtained by the player for the round, separated with a space. The name contains not less than 1 and no more than 10 characters. The name consists of lowercase Latin letters only. It is guaranteed that any two different players have different names. The amount of points, obtained by the player for the round, is a non-negative integer number and does not exceed 1000.

Output

Print on the first line the number m — the number of players, who participated in one round at least.

Each one of the next m lines should contain a player name and a category he belongs to, separated with space. Category can be one of the following: "noob", "random", "average", "hardcore" or "pro" (without quotes). The name of each player should be printed only once. Player names with respective categories can be printed in an arbitrary order.

Sample Input

5 vasya 100 vasya 200 artem 100 kolya 200 igor 250

Sample Output

4 artem noob igor pro kolya random vasya random

题意

给你n个数据，每个数据有名字和分数，但是只用考虑最高分数

如果这个人的分数比99%的人都高，那就是pro

。。。。（然后读题，读题

然后让你输出有多少个人，并且把每个人获得的称号输出

题解：

水题咯，直接n^2就好了~
