How to trim leading and trailing whitespace from a string in Golang?

In Golang, you can use the strings.TrimSpace() function to trim leading and trailing whitespace from a string.

Here's an example:

package main

import (
	"fmt"
	"strings"
)

func main() {
	str := "   Hello, World!   "
	trimmedStr := strings.TrimSpace(str)
	fmt.Printf("Original string: %s\n", str)
	fmt.Printf("Trimmed string: %s\n", trimmedStr)
}

This will output:

Original string:    Hello, World!   
Trimmed string: Hello, World!

As you can see, the strings.TrimSpace() function removes the leading and trailing whitespace from the string.
