从键盘输入某班学生的学号和某门课的成绩（每班人数最多不超过40人），当输入为负值时，表示输入结束，试编程从键盘任意输入一个学号，查找该学号学生的成绩。

**提示信息："Input student’s ID and score:"
**输入格式： "%ld%d" 
**提示信息： "Input the searching ID:" 
**输入格式要求："%ld" 
**输出格式要求："Total students are %dn"
                            "score = %dn"         "Not found!n"
程序的两次运行示例如下：
① Input student’s ID and score:1910122 84
Input student’s ID and score:1910123 83
Input student’s ID and score:1910124 88
Input student’s ID and score:1910125 87
Input student’s ID and score:1910126 61
Input student’s ID and score:-1 -1
Total students are 5
Input the searching ID:1910123
score =  83
②  Input student’s ID and score:1910122 84
Input student’s ID and score:1910123 83
Input student’s ID and score:1910124 88
Input student’s ID and score:1910125 87
Input student’s ID and score:1910126 61
Input student’s ID and score:-1 -1
