            result[i] = 0;
        }

        for (int i = 0; i < n; i++) {

            for (String x : num) {
                result[Integer.parseInt(x)] = result[Integer.parseInt(x)] + 1;
            }
        }

        for (int i = 0; i < L-1; i++) {
            System.out.print(result[i]+" ");
        }
