What collision resolution methods are implemented in the Go language?

In the Go language, chaining is used to resolve collisions in hash tables (for example, in the implementation of map). This means that when key collisions occur, elements with the same hash are stored in a linked list or another data structure associated with a single array cell.

Go does not use open addressing or double hashing in its standard map implementation. Instead, when a collision occurs, new elements are added to the chain, which allows efficient handling of collisions and maintaining performance.

An example of the concept (simplified):

// map implemented as an array of buckets
// each bucket contains a linked list of elements with the same hash
// when adding an element, if the bucket is occupied, the element is added to the chain
