/*Question - Maximum number in array using user defined method.*/
//Ans:

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter no of elements:");

        System.out.println("Enter elements:");
        int[] array = new int[20];
        for(int i=0;i<n;i++){
            array[i]=sc.nextInt();
        }
        System.out.println("*** Initial Array ***");
        for (int i=0; i<n; i++)
        {
            System.out.print(" "+array[i]);
        }
        System.out.println("\nMaximum number is");
        max(array,n);
    }
    
    //Method to print maximun no of array 
    public static void max(int[] arr , int size){
