sort.Strings()

The Strings() function is an inbuilt function of the sort package which is used to sort a given slice of Strings (string type of elements) in increasing order (ascending order).

It accepts a parameter (x []string) and returns nothing.

Syntax

func Strings(x []string)

Parameters

• x : Slice of Strings to be sorted in ascending order.

Return Value

None.

Example 1

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

package main

import (
	"fmt"
	"sort"
)

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

	fmt.Println()

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

Output:

x (Before): [Banana Apple Cat Mango]
x (After): [Apple Banana Cat Mango]

x (Before): [Tigor Venue City Creta]
x (After): [City Creta Tigor Venue]

Example 2

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

package main

import (
	"fmt"
	"sort"
)

func main() {
	x := []string{"Banana", "Apple", "Cat", "Mango"}
	// Printing x, type, sorting status
	fmt.Println("x:", x)
	fmt.Printf("%T, %v\n", x, sort.StringsAreSorted(x))

	// Sorting x
	sort.Strings(x)

	// Printing x, type, sorting status
	fmt.Println("x:", x)
	fmt.Printf("%T, %v\n", x, sort.StringsAreSorted(x))

	fmt.Println()

	x = []string{"Tigor", "Venue", "City", "Creta"}

	// Printing x, type, sorting status
	fmt.Println("x:", x)
	fmt.Printf("%T, %v\n", x, sort.StringsAreSorted(x))

	// Sorting x
	sort.Strings(x)

	// Printing x, type, sorting status
	fmt.Println("x:", x)
	fmt.Printf("%T, %v\n", x, sort.StringsAreSorted(x))
}

Output:

x: [Banana Apple Cat Mango]
[]string, false
x: [Apple Banana Cat Mango]
[]string, true

x: [Tigor Venue City Creta]
[]string, false
x: [City Creta Tigor Venue]
[]string, true
