    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter length: ");
        int l = scanner.nextInt();
        System.out.println("Enter array: ");
        int[] array = new int[l * 2];
        for (int i = 0; i < array.length; i++) {
            array[i] = scanner.nextInt();
        }
        int ans = 0;
        for (int i = 0; i < array.length; i = i + 2) {
            ans = ans + (array[i + 1] - array[i]);
        }
        System.out.println("Street covered with light: " + ans);
    }
