What is the maximum number of elements a single Bucket can contain in a hash map implementation?

In the implementation of a hash map (hash table), one bucket usually represents a list or another structure for storing collisions. The maximum number of elements in a single bucket is theoretically unlimited — it depends on the number of collisions and the chosen data structure.

In practice, if the hash function distributes keys evenly, the number of elements in a bucket will be small (usually 1-2). If collisions are frequent, a bucket can contain many elements, which reduces performance.

In Go, the standard map implementation is hidden but uses complex structures with dynamic reallocation to minimize the length of a bucket. In simple implementations, a bucket is a linked list or slice that can grow to any size until reorganization is performed.
