How to convert a string to lowercase in Golang?

In Golang, you can convert a string to lowercase using the strings package which provides a ToLower function. Here's an example:

package main

import (
	"fmt"
	"strings"
)

func main() {
	str := "HELLO WORLD"

	// Convert to lowercase
	str = strings.ToLower(str)

	fmt.Println(str) // Output: hello world
}

In this example, strings.ToLower function is used to convert the string HELLO WORLD to lowercase. The resulting lowercase string is then printed.
