Highly Rated Courses Filter

You are given a number of courses and their corresponding ratings. For each course, compute its average rating using the formula \(\text{average} = \frac{\sum ratings}{\text{number of ratings}}\). A course is considered highly rated if its average rating is at least 4.0.

Your task is to output the indices (0-indexed) of all highly rated courses in increasing order. If no course qualifies, print an empty line.

Input format: The first line contains an integer \(N\) representing the number of courses. Each of the next \(N\) lines contains a space-separated list of integers denoting the ratings for that course.

Output format: Print a single line containing the indices of the courses that are highly rated, separated by a single space. If there is no such course, output an empty line.
