HackerRank - Python Introduction to Sets
Let's use our knowledge of sets and help Mickey.
Ms. Gabriel Williams is a botany professor at District College. One day, she asked her student Mickey to compute the average of all the plants with distinct heights in her greenhouse.
- def average(heights):
- heights = set(heights)
- return sum(heights) / len(heights)
-
- if __name__ == '__main__':
- n = int(input())
- arr = list(map(int, input().split()))
- result = average(arr)
- print(result)
