写在前面
- 思路分析
- string型female和male保存要求的学生信息
- int型fscore和mscore保存男生最低分和女生最高分
- 初始化fscore-1, mscore为最大值101
- 根据性别、分数大小迭代更新:
- female和male
- fscore和mscore
- 题目简单,不再赘述
- 15分钟a题目
测试用例
-
input: 3 Joe M Math990112 89 Mike M CS991301 100 Mary F EE990830 95 output: Mary EE990830 Joe Math990112 6 input: 1 Jean M AA980920 60 output: Absent Jean AA980920 NA

#include <iostream> using namespace std; int main() { int n; scanf("%d", &n); string female, male; int fscore = -1, mscore = 101; for(int i=0; i<n; i++) { string name, sex, num; int score; cin >> name >> sex >> num; scanf("%d", &score); if(sex == "F") { if(fscore < score) { fscore = score; female = name + " " + num; } } else if (mscore > score) { mscore = score; male = name + " " + num; } } if(fscore != -1) cout << female << endl; else printf("Absent\n"); if(mscore != 101) cout << male << endl; else printf("Absent\n"); if(mscore != 101 && fscore != -1) printf("%d", fscore-mscore); else printf("NA\n"); return 0; }
