Does using a Map data structure guarantee constant time for element search?

In Go, the data structure map provides amortized access time to elements, close to constant time (O(1)) on average. However, this does not guarantee strictly constant search speed, as in worst cases (for example, with a large number of hash collisions), access time can deteriorate.

Thus, map in Go offers very fast, but not absolutely constant, search speed.

Example of using map in Go:

m := make(map[string]int)
m["apple"] = 5
value, ok := m["apple"]
if ok {
    fmt.Println("Value:", value)
}
