Transform array in java.

 Given an array with N distinct all are positive elements, convert the given array to a form where all elements are in the range from 0 to N-1. The order of elements is the same, i.e., 0 is placed in the place of the smallest element, 1 is placed for the second smallest element, … N-1 is placed for the largest element.

 import java.util.Scanner;

public class code

{

    public static void main(String[] args) {

    Scanner sc = new Scanner(System.in);

    System.out.println("enter size of array=");

    int n=sc.nextInt();

    int[] arr=new int[n];

    System.out.println("enter elements of array=");

    for(int i=0; i<n; i++){

        arr[i]=sc.nextInt();

    }

    int x=0;

    for(int i=0; i<n; i++){

        int min=Integer.MAX_VALUE;

        int index=-1;

        for(int j=0; j<n; j++){

            if(arr[j]<min && arr[j]>0){

                min=arr[j];

                index=j;

            }

        }

        arr[index]=x;

        x--;

    }

    System.out.println("transform array is=");

    for(int ele : arr){

        System.out.print(-1*ele+" ");

    }

}
