Write a program to calculate average scores.
Suppose there are s students taking the same c courses. The program should compute the average score for each student, as well as the average score for each course across all students.
Input:
The following s lines each represent one student’s scores. Each line contains c numbers, where the j-th number represents that student’s score in the j-th course.
Output:
A total of s + c lines.
The first s lines each contain the average score of one student.
The next c lines each contain the average score of one course across all students.
Constraints:
0 < s ≤ 100
0 < c ≤ 100
First line: s, c.
Following s lines each represent one student's score, c represents the student's score in the j-th course.
Ex. 3 4
87 89 97 89
78 100 76 98
99 90 89 94
A total of s + c lines.
The first s lines each contain the average score of one student.
The next c lines each contain the average score of one course across all students.
Ex. 90
88
93
88
