1056. Mice and Rice (25)

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

题目大意：就是比赛轮询。例子的演示结果如下

#include<iostream>
#include<cstdio>
#include<vector>
using namespace std;
int main(){
	vector<int>rank;
	vector<int>m_order;
	vector<int>rice;
	int np,ng;
	scanf("%d%d",&np,&ng);
	int i,j;
	int val;
	rank.resize(np);
	for(i=0;i<np;i++){
		scanf("%d",&val);
		rice.push_back(val);
	}
	for(i=0;i<np;i++){
		scanf("%d",&val);
		m_order.push_back(val);
	}
	while(m_order.size()>1){
		int len = m_order.size();
		int currank=len/ng+1;
		if(len%ng){
			currank++;
		}
		vector<int>next;
		next.clear();
		int k=0;
		while(k<len){
			int max=-1,index=0;
			for(i=0;i<ng&&k<len;i++,k++){

		}

	}
	if(m_order.size()){
		rank[m_order[0]]=1;
	}
	printf("%d",rank[0]);
	for(i=1;i<np;i++){
