Kuidas hinnata elemendi sisestamise operatsiooni ajakulutust hash-tabelis?

The average time complexity of inserting an element into a hash table is O(1) — constant time. This is achieved by computing the hash function for the key and inserting the element into the corresponding bucket.

However, in the worst case, when many collisions occur and all elements fall into a single bucket (for example, due to a poor hash function or high load factor), the complexity can degrade to O(n), where n is the number of elements in the table.

To maintain efficiency, collision resolution methods (chaining, open addressing) and dynamic resizing of the table are typically used when a certain load factor is reached.
