Problem Description
The Annual National Olympic of Information(NOI) will be held.The province of Shandong hold a Select(which we call SDOI for short) to choose some people to go to the NOI. n(n≤100) people comes to the Select and there is m(m≤50) people who can go to the NOI.
According to the tradition and regulation.There were two rounds of the SDOI, they are so called "Round 1" and "Round 2", the full marks of each round is300 .
All the n people take part in Round1 and Round2, now the original mark of every person is known. The rule of SDOI of ranking gets to the "standard mark". For each round there is a highest original mark,let's assume that isx .(it is promised that not all person in one round is 0,in another way,x>0 ). So for this round,everyone's final mark equals to his/her original mark∗(300/x) .
After we got everyone's final mark in both round.We calculate the Ultimate mark of everyone as0.3∗round1′s final mark + 0.7∗round2′s final mark.It is so great that there were no two persons who have the same Ultimate mark.
After we got everyone's Ultimate mark.We choose the persons as followed:
To encourage girls to take part in the Olympic of Information.In each province,there has to be a girl in its teams.
1. If there is no girls take part in SDOI,The boys with the rank of first m enter the team.
2. If there is girls, then the girl who had the highest score(compared with other girls) enter the team,and other(boys and other girls) m-1 people with the highest mark enter the team.
Just now all the examination had been finished.Please write a program, according to the input information of every people(Name, Sex ,The original mark of Round1 and Round2),Output the List of who can enter the team with their Ultimate mark decreasing.

Just now all the examination had been finished.Please write a program, according to the input information of every people(Name, Sex ,The original mark of Round1 and Round2),Output the List of who can enter the team with their Ultimate mark decreasing.
Input
There is an integer T(T≤100) in the first line for the number of testcases and followed T testcases.
For each testcase, there are two integersn and m in the first line(n≥m) , standing for the number of people take part in SDOI and the allowance of the team.Followed with n lines,each line is an information of a person. Name(A string with length less than 20 ,only contain numbers and English letters),Sex(male or female),the Original mark of Round1 and Round2 (both equal to or less than 300 ) separated with a space.
For each testcase, there are two integers
Output
For each testcase, output "The member list of Shandong team is as follows:" without Quotation marks.
Followedm lines,every line is the name of the team with their Ultimate mark decreasing.
Followed

英文太长,看都不想看,题看错了,wa了,也不行检查,这样会死的啊!!!
题意:n个人找m个参加比赛,有女生有“优惠”。
1,判断有无女生,没有直接输出。有再做处理:先输出m-1项,判断里面有无女生,有直接输出m项。无,输出女生中最高的。#include<cstdio>#include<cstring>#include<algorithm>using namespace std;struct people{char name[110];char xb[10];double a,b;double mark;//注意有除法,double型 }a[110],b[110];bool cmp(people a,people b){return a.mark>b.mark;}int main(){int t,x,y,z,ant;scanf("%d",&t);while(t--){x=0,y=0,ant=0;//x,y 用于两次判断有无女生的变量 double max1=0,max2=0;//根据题意找出第一,第二的最高成绩 int n,m;scanf("%d %d",&n,&m);for(int i=0;i<n;i++){scanf("%s %s %lf %lf",a[i].name,a[i].xb,&a[i].a,&a[i].b);max1=max(max1,a[i].a);max2=max(max2,a[i].b);}max1=300.0/max1;max2=300.0/max2;for(int i=0;i<n;i++){a[i].mark=0.3*a[i].a*max1+0.7*a[i].b*max2;int A=strcmp(a[i].xb,"female");if(A==0)//第一次判断又无女生,有为1 x=1;}sort(a,a+n,cmp);if(x==0)//没有女生直接输出 {printf("The member list of Shandong team is as follows:\n");for(int i=0;i<m;i++)printf("%s\n",a[i].name);} else{printf("The member list of Shandong team is as follows:\n");for(int i=0;i<m-1;i++){printf("%s\n",a[i].name);//有女生,先输出前m-1个 int A=strcmp(a[i].xb,"female");if(A==0) y=1;}if(y!=0)printf("%s\n",a[m-1].name);//判断前m-1个有无女生,有直接输出第m个else{for(int i=0;i<n;i++){int A=strcmp(a[i].xb,"female");if(A==0)//前m-1个没有女生要输出成绩最高的女生,把所有女生成绩重新存入b数组 {b[ant].mark=a[i].mark;ant++;}}sort(b,b+ant,cmp);//找到女生成绩最高的 for(int i=0;i<n;i++){if(b[0].mark==a[i].mark){z=i;break;//找到女生是多少,然后输出名字 }}printf("%s\n",a[z].name);}} }return 0;}
