How do I delete a key from a map in Go?

In Go, you can delete a key from a map using the built-in `delete` function. This function takes two arguments: the map and the key you want to remove. If the key exists in the map, it will be removed; if the key does not exist, nothing happens.

Here’s a simple example to illustrate how to delete a key from a map:


package main

import "fmt"

func main() {
    // Create a map
    myMap := map[string]int{
        "apple":  1,
        "banana": 2,
        "cherry": 3,
    }

    // Print the original map
    fmt.Println("Original map:", myMap)

    // Delete the key "banana"
    delete(myMap, "banana")

    // Print the modified map
    fmt.Println("Modified map:", myMap)
}

In this example, after deleting the key "banana", the map will only contain the keys "apple" and "cherry".
