读入 n（>0）名学生的姓名、学号、成绩，分别输出成绩最高和成绩最低学生的姓名和学号。

输入格式：

每个测试输入包含 1 个测试用例，格式为

第 1 行：正整数 n
第 2 行：第 1 个学生的姓名 学号 成绩
第 3 行：第 2 个学生的姓名 学号 成绩
  ... ... ...
第 n+1 行：第 n 个学生的姓名 学号 成绩

其中姓名和学号均为不超过 10 个字符的字符串，成绩为 0 到 100 之间的一个整数，这里保证在一组测试用例中没有两个学生的成绩是相同的。

输出格式：

对每个测试用例输出 2 行，第 1 行是成绩最高学生的姓名和学号，第 2 行是成绩最低学生的姓名和学号，字符串间有 1 空格。

输入样例：

3
Joe Math990112 89
Mike CS991301 100
Mary EE990830 95

输出样例：

Mike CS991301
Joe Math990112

编程语言：Python

解题思想：

1.使用列表存储三个字段的值

2.对成绩进行判断并保留列表索引

时间复杂度：O(n)

代码如下：

NOP = int(input())
Student = [["Name", "ID", "Score"] for i in range(NOP)]  # 创建姓名、学号、成绩的列表
MaxScore, MinScore, MaxIndex, MinIndex = 0, 100, 0, 0  # 初始化最高成绩和最低成绩、最高成绩和最低成绩对应的学生在列表中的索引
for i in range(NOP):
    Student[i] = list(map(str, input().split()))
    if int(Student[i][2]) > MaxScore:  # 出现更高成绩
        MaxScore = int(Student[i][2])
        MaxIndex = i
    if int(Student[i][2]) < MinScore:  # 出现更低成绩
        MinScore = int(Student[i][2])
        MinIndex = i
print(Student[MaxIndex][0], Student[MaxIndex][1])  # 输出最高成绩学生姓名和学号
print(Student[MinIndex][0], Student[MinIndex][1])  # 输出最低成绩学生姓名和学号
