    Question

    Python's built-in dict (dictionary) data structure is

    typically implemented using a hash table. What is the average-case time complexity for get, set, and del operations in a Python dictionary?
    A O(N) Correct Answer Incorrect Answer
    B O(log N) Correct Answer Incorrect Answer
    C O(1) Correct Answer Incorrect Answer
    D O(N log N) Correct Answer Incorrect Answer
    E O(N^2) Correct Answer Incorrect Answer

    Solution

    Python's dict is implemented as a hash table. On average, operations like get, set (insertion/update), and del (deletion) have a constant time complexity, O(1), assuming a good hash function and effective collision resolution.
