find the keys of a map in go

In Go, to find the keys of a map, you can use the range keyword to iterate over the map, and the for ... range ... loop syntax. Within the loop, you can access the keys of the map.

Here's an example:

main.go
// create a test map
m := map[string]int{"a": 1, "b": 2, "c": 3}

// iterate over the map and print the keys
for key := range m {
    fmt.Println(key)
}
153 chars
8 lines

Output:

main.go
a
b
c
6 chars
4 lines

In this example, we create a map with key-value pairs "a": 1, "b": 2, "c": 3. Then, we use the for ... range ... loop to iterate over the map, and assign the key to the variable key. Each time through the loop, we print the value of key, which will be the keys of the map.
