        String key = "" + str.charAt(24) + str.charAt(39) + str.charAt(35) + str.charAt(88) + str.charAt(98) + str.charAt(24) + str.charAt(13) + str.charAt(59);
        System.out.println(key);
        byte[] bytes = str.getBytes(StandardCharsets.UTF_8);
        int[] arr = new int[26];
        for (int i = 0; i < bytes.length; i++) {
            arr[bytes[i] - 97] ++;
        }
        for (int i = 0; i < arr.length; i++) {
            System.out.println((char)(i+97) + "的个数为：" + arr[i]);
        }
