Question

Create a Kotlin console program that satisfies the following 1. The program prompts a user to enter a number that is used to create an array with the number of elements. 2. The program asks the user to enter a series of numbers, and the numbers are to be entered and stored in the array 3. The program asks the user to select the way of how the numbers are sorted, le, ascending or descending of the user enters a, the numbers are sorted in ascending order and displayed of the user enters d, the numbers are sorted in descending order and displayed. 4. The program asks the user whether he/she wants to continue. If the user enters Corc, the program continues and repeats the process again. If the user enters any other key, the program stops Enter . positive integer 3 Enter sten 11 Enter Iten 22 Enter ten 31 You have entered 4 27 Enter for Ascending or a cor descendingia The number in Ascending order To continue, antex a to quit, enter any other kaya Enter . positive Integer Enter ten l! 7 Enter sten 25 Enter ten 41 You have entered 7 639 Enter a fox ascending, or a cor descending: a The numbers in descending order! To continue, antex a to quit, enter any other keyg The End Your code should conform to the following requirement: 1. At the beginning of your code, include your affidavit statement as comments 2. Do not use Kotlin's default methods to sort numbers. You must create your own methods (with appropriate algorithms) to sort numbers. 3. Use the default package. Do not create your own packages 4. The algorithms for sorting numbers should be managed in separate functions (eg, sortAscending) and

4. the algorithims for sorting numbers should be managed in separate functions (e.g., sortAscending() and sortDescending())

Answer 1

//Create a kotlin file and save the file as sorting.kt
The below kotlin program prompts user to enter the size of items to read and then prompts user to enter the items and store the item values in an array.Then prompts user to enter the choice for sorting ,a for ascendig or d for descending sorting. Then prompt user to continue or q to quit.
//The software used to run this program is  Intelli-IDEA
//sorting.kt
fun main()
{
    var repeat=true
    while (repeat)
    {

        var numItems = 0
        print("Enter a positive integer :")
        //read size in numItems
        numItems = Integer.parseInt(readLine())
        //create an array of given size
        val item_array = IntArray(numItems)

        //read numbers and store in array 
        for (x in 0..numItems - 1) {
            print("Enter item $x : ")
            var num = Integer.parseInt(readLine())
            item_array[x] = num
        }

        print("You have entered ")
        //print numbers 
        for (x in item_array) {
            print(" $x")
        }
        println()
        print("Enter a for ascending , or d for descending :")
        //read user choice for ascending or d for descending order 
        var choice = readLine()
        if (choice.equals("a"))
            //call sortAscending function
            sortAscending(item_array)
            print("The numbers in ascending order :")
            for (x in item_array)
                print(" $x")
        println()
        
        //check if user enters d for descending sorting
        if (choice.equals("d"))
        //call sortDescending function
            sortDescending(item_array)
        print("The numbers in desending order :")
        for (x in item_array)
            print(" $x")
        println()
        print("To continue, Enter c ; To quit, enter anyther key")
       var userchoice= readLine()

        if (userchoice.equals("q"))
            repeat=false
    }
}
//The function that takes an integer array and sorts the numbres
//in asending order and returns the sorted numbers
fun sortAscending(arr :IntArray):IntArray
{
    var swap = true
    while(swap)
    {
        swap = false
        for(i in 0 until arr.size-1)
        {
            if(arr[i] > arr[i+1]){
                val temp = arr[i]
                arr[i] = arr[i+1]
                arr[i + 1] = temp

                swap = true
            }
        }
    }
    return arr
}
//The function that takes an integer array and sorts the numbres
//in descending order and returns the sorted numbers
fun sortDescending(arr :IntArray):IntArray
{
    var swap = true
    while(swap)
    {
        swap = false
        for(i in 0 until arr.size-1)
        {
            if(arr[i] < arr[i+1]){
                val temp = arr[i]
                arr[i] = arr[i+1]
                arr[i + 1] = temp

                swap = true
            }
        }
    }
    return arr
}
