Mice and Rice is the name of a programming contest in which each programmer must write a piece of code to control the movements of a mouse in a given map. The goal of each mouse is to eat as much rice as possible in order to become a FatMouse.
First the playing order is randomly decided for N P programmers. Then every N G programmers are grouped in a match. The fattest mouse in a group wins and enters the next turn. All the losers in this turn are ranked the same. Every N G winners are then grouped in the next match until a final winner is determined.
For the sake of simplicity, assume that the weight of each mouse is fixed once the programmer submits his/her code. Given the weights of all the mice and the initial playing order, you are supposed to output the ranks for the programmers.
Input Specification:
Each input file contains one test case. For each case, the first line contains 2 positive integers: N P and N G (≤1000), the number of programmers and the maximum number of mice in a group, respectively. If there are less than N G mice at the end of the player’s list, then all the mice left will be put into the last group. The second line contains N P distinct non-negative numbers W i (i=0,⋯,N P − 1) where each W i is the weight of the i-th mouse respectively. The third line gives the initial playing order which is a permutation of 0,⋯,N P − 1 (assume that the programmers are numbered from 0 to N P - 1). All the numbers in a line are separated by a space.
Output Specification:
For each test case, print the final ranks in a line. The i-th number is the rank of the i-th programmer, and all the numbers must be separated by a space, with no extra space at the end of the line.
Sample Input:
11 3
25 18 0 46 37 3 19 22 57 56 10
6 0 8 7 10 5 9 1 4 2 3
Sample Output:
5 5 5 2 5 5 5 3 1 3 5
注意点
在计算当前循环所要确定的排名时,需要分为是否能整除两种情况:
- 如果剩下还未确定排名的数量(len)不能整除每组的人数(ng),则该轮循环可以确定的排名是 len / ng + 2
- 否则,该轮循环可以确定的排名是 len / ng + 1
