Task

Finish the code for the second parameter of the operate function, which is expected to accept the capitalize function;
Review the code and provide suitable arguments in the operate function call within the main() function;
Save the returned values from the operate function call into the variables original and updated.

package main
import "fmt"

// `ToLower()` and `ToUpper()` functions are imported from the `strings` module
import "strings"

func capitalize(str string) string {
    return strings.ToUpper(str)
}

func operate(str string, operation ___) (string, string) {
    return str, operation(str)
}
