Q4
Question:
One of your professors needs assistance. He wants to write
a program to calculate the average of students and to
count the number of students whose average is above (<) a given
grade (k). The professor calculates the averages as follows,
65 percent of the highest grade and 35 percent of the lowest
grade. Every student has at most 10 grades where the grades
are integers between 30 and 100. The max grade is calculated
as regular: max of the given grades. On the other hand, to
calculate the min regularly, the student must have at least
6 grades. If a student has less than 6 grades, his min is
taken as 0.
Input specification:
You will be given two integers in the beginning:
The number of students (n) and the grade (k) above which
you are going to count the number of students. The following
n lines will have at most 10 integers (integers between 30
and 100) separated by a comma where the last grade is
followed by a semicolon. n is an integer 1 and 10,000
and k is between 1 and 100.
Output specification:
Show one integer.

Explanation:
The first student has seven grades where his
min is 36 and his max is 98. Thus his average
will be 76.3. The table on the right gives the
information about average calculation for each
student.
