Hashing Questions Medium
The time complexity of inserting and deleting elements in a hash table is typically O(1) on average. This means that the time it takes to insert or delete an element from a hash table does not depend on the size of the table. However, in the worst case scenario, the time complexity can be O(n), where n is the number of elements in the hash table. This occurs when there are many collisions, resulting in a long chain of elements in the same hash bucket. In such cases, the hash table may need to be resized or rehashed, which can take linear time. Overall, the average time complexity for inserting and deleting elements in a hash table is constant, making it an efficient data structure for these operations.
