Description
You have 2 tables, courses and scores . courses consists 3 columns, sid , student_id , and course_id . scores consists 2 columns, sid and score. Please find that how many students failed on at least one
course
你有2個表單, courses 和scores。
courses 有3個欄位,sid、student_id、course_id。 scores 有2個欄位,sid 和score。請分析有多少學生被當掉至少一科。
Input
First line consists 2 integers m and n, shows number of rows in courses and scores .
Followed m lines are records of courses . student id are 8-digits numbers begin with non-zero digit. sid and scores are positive integers smaller than 1000.
Followed n lines are records of scores . sid are positive integers smaller than 1000. score are integers in range [0, 100].
第一行有2個整數 m 和n,代表courses 和 scores 中有多少行。
接著的 m行是 courses 的内容。 student_id 是個非0開頭的8位數字。sid和 scores 是個未滿 1000的正整數。
接著的n行是scores 的内容。 sid 是個未滿1000的正整數。score 是介於 [0, 100] 間的整數。
Output
Student will be flunked when his/her average score in the course less than 60. Output is 2 integers shows number of student and student failed on at lease one course.
學生若該科的平均分數未滿60 分則他她該科會被當。輸出包含2個整數,分別是學生人數和至少有一科被當的學生人數。
