Example 1

// Golang program to demonstrate the
// example of sort.StringsAreSorted() Function

package main

import (
	"fmt"
	"sort"
)

func main() {
	x := []string{"Banana", "Apple", "Cat", "Mango"}
	fmt.Println("x:", x)
	fmt.Println("sort.StringsAreSorted(x):",
		sort.StringsAreSorted(x))
	fmt.Println()

	x = []string{"City", "Creta", "Tigor", "Venue"}
	fmt.Println("x:", x)
	fmt.Println("sort.StringsAreSorted(x):",
		sort.StringsAreSorted(x))
}

Output:

x: [Banana Apple Cat Mango]
sort.StringsAreSorted(x): false

x: [City Creta Tigor Venue]
sort.StringsAreSorted(x): true

Example 2

// Golang program to demonstrate the
// example of sort.StringsAreSorted() Function

package main

import (
	"fmt"
	"sort"
)

func main() {
	x := []string{"Banana", "Apple", "Cat", "Mango"}
	fmt.Println("x:", x)

	// Checking whether x is sorted or not,
	// if not sorted then sorting the x, and printing
	if sort.StringsAreSorted(x) == true {
		fmt.Println("Elements are already sorted")
	} else {
		fmt.Println("Elements are not sorted")
		fmt.Println("Sorting....")
		sort.Strings(x)
		fmt.Println("Sorting done.")
		fmt.Println("x:", x)
	}
	fmt.Println()

	x = []string{"City", "Creta", "Tigor", "Venue"}
	fmt.Println("x:", x)

	// Checking whether x is sorted or not,
	// if not sorted then sorting the x
	// and printing
	if sort.StringsAreSorted(x) == true {
		fmt.Println("Elements are already sorted")
	} else {
		fmt.Println("Elements are not sorted")
		fmt.Println("Sorting....")
		sort.Strings(x)
		fmt.Println("Sorting done.")
		fmt.Println("x:", x)
	}
}

Output:

x: [Banana Apple Cat Mango]
Elements are not sorted
Sorting....
Sorting done.
x: [Apple Banana Cat Mango]

x: [City Creta Tigor Venue]
Elements are already sorted
