1036 Boys vs Girls （男孩vs女孩）

This time you are asked to tell the difference between the lowest grade of all the male students and the highest grade of all the female students.

Input Specification:

Each input file contains one test case. Each case contains a positive integer N, followed by N lines of student information. Each line contains a student’s name, gender, ID and grade, separated by a space, where name and ID are strings of no more than 10 characters with no space, gender is either F (female) or M (male), and grade is an integer between 0 and 100. It is guaranteed that all the grades are distinct.

Output Specification:

For each test case, output in 3 lines. The first line gives the name and ID of the female student with the highest grade, and the second line gives that of the male student with the lowest grade. The third line gives the difference gradeF-gradeM. If one such kind of student is missing, output “Absent” in the corresponding line, and output “NA” in the third line instead.

Sample Output 1:

Sample Input 2:

1 Jean M AA 60

Sample Output 2:

讯享网Absent Jean AA NA

题目大意：

给出N个同学的信息，输出女生中的最高分获得者的信息与男生中最低分获得者的信息，并输出他们的分数差Girl.grade - Boy.grade。如果不存在女生或者男生，则对应获得者信息处输出Absent，而且差值处输出NA。

思路：

Boy、Girl两个结构体分别存储男生中的最低分的信息与女生中的最高分的信息；每次输入时对比，若是男生且text.grade < Boy.grade，则更新Boy结构体信息，若是女生且text.grade > Girl.grade，则更新Girl结构体的信息。

代码：

#include<stdio.h> #include<string.h> typedef struct node{ 
    char name[10]; char gender; char ID[10]; int grade; }Node; int main(){ 
    int n, i, flag = 1; scanf("%d", &n); Node text, Boy, Girl; Boy.grade = 101; Girl.grade = -1; for(i = 0; i < n; i++){ 
    getchar(); scanf("%s %s %s %d", text.name, &text.gender, text.ID, &text.grade); if(text.gender == 'F' && text.grade > Girl.grade){ 
    strcpy(Girl.name, text.name); strcpy(Girl.ID, text.ID); Girl.grade = text.grade; } if(text.gender == 'M' && text.grade < Boy.grade){ 
    strcpy(Boy.name, text.name); strcpy(Boy.ID, text.ID); Boy.grade = text.grade; } } if(Girl.grade == -1){ 
    printf("Absent\n"); flag = 0; } else{ 
    printf("%s %s\n", Girl.name, Girl.ID); } if(Boy.grade == 101){ 
    printf("Absent\n"); flag = 0; } else{ 
    printf("%s %s\n", Boy.name, Boy.ID); } if(flag == 0) printf("NA\n"); else printf("%d\n", Girl.grade - Boy.grade); return 0; }
