Analyze time complexity for dictionary operations
Analyze Time Complexity for Dictionary Operations
Analyze the time complexity of the following dictionary/hash map operations:
(a) Searching for a key: State the average-case and worst-case time complexity. Explain how factors such as hashing function quality, collision handling strategies (e.g., chaining vs. open addressing), load factor, and resizing impact the runtime and constant factors.
(b) Copying all keys into a list: State the time and extra space complexity in Big-O notation. Discuss the costs associated with iteration, allocation and resizing for the list, and any differences for ordered dictionaries.
Assume a conventional hash table implementation and a dynamic array-backed list.
