            array[i]  = scanner.nextInt();
        }
        System.out.println("Enter a number to be searched:  ");
        int el = scanner.nextInt();
        int ans = find(array, el);
        if (ans == -1) {
            System.out.println("Element not found");
        } else {
            System.out.println(el + " found in location " + (ans + 1));
