What is the complexity of implementing element removal in a HashSet data structure?

Answer from AI
Removing an element in a HashSet data structure typically has an amortized time complexity of O(1). This is achieved because HashSet uses a hash table to store elements, which allows for quick lookup and removal of elements by their hash. However, in the worst case, with a large number of collisions, the complexity can degrade to O(n), where n is the number of elements in the set.
