Submitted by Nidhi, on April 29, 2021

Problem Solution:

Here, we will shuffle the words of a string using the rand.Shuffle() function and print the result on the console screen.

Program/Source Code:

The source code to shuffle words of a string is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Golang program to shuffle words
// of a string

package main

import "math/rand"
import "fmt"
import "strings"

//Entry point for the program
func main() {
	str := strings.Fields("Honesty is the best policy")

	rand.Shuffle(len(str), func(a, b int) {
		str[a], str[b] = str[a], str[b]
	})
	fmt.Printf("Shuffled string: \n%s\n", str)

}

Output:

Shuffled string:
[Honesty is the best policy]

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 required packages to predefined functions.

In the main() function, we used the rand.Shuffle() function to shuffle substrings or words with the string and printed the result on the console screen.
