Time complexity of hashmap operations is O(1) on average, but can be O(n) in worst case scenarios.
HashMap operations like get, put, and remove have constant time complexity O(1) on average due to hashing.
In worst case scenarios, when there are many collisions, time complexity can degrade to O(n) where n is the number of elements in the hashmap.
Hashing function quality and load factor affect the time complexity of hashm
