Gradebook Top Student

Each row of scores holds one student's test scores. Compute each student's average with a helper function and return the row index of the student with the highest average. If several tie, return the smallest index.

Implement top_student(scores).

Input

scores: One row of scores per student; every row has at least one score.

Output

Return the index of the top student.
