Millist tüüpi andmed või elemendid võivad olla Bucket struktuuri lõpus?

In the Bucket structure in Go, which is often used in hash tables (for example, in the implementation of map), there can be at the end a pointer or reference to the next element (the next bucket) to resolve collisions by chaining. This allows storing multiple elements with the same hash in a linked list.

Simplified example of a Bucket structure:

type Bucket struct {
    key   string
    value interface{}
    next  *Bucket // pointer to the next bucket in the chain
}

Thus, at the end of the structure, there is usually a reference to the next element, ensuring connectivity and the ability to traverse all elements with the same hash.
