Optimizing sum of unique elements

Report a typo

Hey there! This problem might be a bit unpredictable, but give it a go and let us know how you do!

You are working on a function calculate_unique_player_scores that calculates the total score of unique player IDs from a massive multiplayer online game (MMO) with billions of players:

def calculate_unique_player_scores(player_scores):
    # TODO: Return the sum of unique player scores
    pass

Each player's score should only be counted once. Which Python collections and methods would you use to implement this function?

Select one option from the list

Use a set to filter player_scores for uniqueness and then apply sum()

Use a dict to count occurrences of each score and then sum the unique scores

Implement a deque to add scores and a loop to sum unique values

Use a list to store scores and employ a loop to sum only unique values

Utilize a tuple for storing scores and a loop to sum unique values, relying on its immutability
