How do I implement a multimap (map of slices) in Go?

In Go, you can implement a multimap (map of slices) using a map where the keys are your desired types and the values are slices of those types. This allows you to store multiple values for each key efficiently.

Here's how you can create and use a multimap in Go:

package main import ( "fmt" ) func main() { // Create a multimap (map of slices) multimap := make(map[string][]int) // Adding values multimap["a"] = append(multimap["a"], 1) multimap["a"] = append(multimap["a"], 2) multimap["b"] = append(multimap["b"], 3) // Display the multimap fmt.Println(multimap) // Accessing values for key, values := range multimap { fmt.Printf("Key: %s, Values: %v\n", key, values) } }
