1056 Mice and Rice

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 NP​ programmers. Then every NG​ 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 NG​ 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: NP​ and NG​ (≤1000), the number of programmers and the maximum number of mice in a group, respectively. If there are less than NG​ 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 NP​ distinct non-negative numbers Wi​ (i=0,⋯,NP​−1) where each Wi​ is the weight of the i-th mouse respectively. The third line gives the initial playing order which is a permutation of 0,⋯,NP​−1 (assume that the programmers are numbered from 0 to NP​−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.

题目大意

// 输入
总人数N 每组M人
N1得分 N2得分 ... NN得分
N个人一开始的出场下标
// 输出
0~N-1下标对应的该人的排名

给你N个人的得分，以及一组的人数K，每个人按出场顺序先分为N/K组，如果N/K有余数，则剩下的人再为一组。

对于每一轮，每组的第一晋级下一轮，且在下一轮的出场顺序同该轮一样，该轮淘汰的所有人排名相同 = 该轮晋级人数 + 1

求每个人的最终排名

思路

  每轮有K组，K=N%M==0 ？ N/M ： N/M+1；

  该组被淘汰人的排名 = 当前人数%M==0 ？ N/M+1 ： N/M+2；
