Checking a slice of integers is sorted or not in Golang

Problem Solution:

In this program, we will create a slice and check the specified slice is sorted or not using IntsAreSorted() and print the appropriate message on the console screen.

Program/Source Code:

The source code to check a specified slice is sorted or not is given below. The given program is compiled and executed successfully.

Golang code to check a specified slice of integers is sorted or not

// Golang program to check a specified slice
// is sorted or not

package main

import "fmt"
import "sort"

func main() {
	var status bool = false

	slice1 := []int{10, 20, 30, 40, 50, 60, 70, 80, 90, 100}
	slice2 := []int{70, 20, 30, 60, 50, 60, 10, 80, 90, 100}

	status = sort.IntsAreSorted(slice1)
	if status == true {
		fmt.Println("Slice1 is sorted")
	} else {
		fmt.Println("Slice1 is not sorted")
	}

	status = sort.IntsAreSorted(slice2)
	if status == true {
		fmt.Println("Slice2 is sorted")
	} else {
		fmt.Println("Slice2 is not sorted")
	}
}

Output:

Slice1 is sorted
Slice2 is not sorted

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the above program, we also imported the sort package to use IntsAreSorted() function to sort string slice.

In the main() function, we created two slices of integers, then we checked slices are sorted or not using the IntsAreSorted() function and then print the appropriate message on the console screen.
