    For any reason the algorithm can't match this line

    start tag --> bbgnEsMIM%9L=E v)f6GjSkSK6W5HWdel)VbBvZRG)#&b=+6k(O9=&C

    value --> rulVew89#uyWF}4`T"xULOZ%1"5Cu)&x7qD0

    end tag --> /bbgnEsMIM%9L=E v)f6GjSkSK6W5HWdel)VbBvZRG)#&b=+6k(O9=&C

    I put it in Intellij and it works well but in Hackerrank page doesn't work, I found out this one in the sample test 3

        String result = "None";
        if (tagMatcher.find()) {
          String tagName = tagMatcher.group(1);
          result = tagMatcher.group(0).replaceAll("<" + tagName + ">", "");
          result = result.substring(0, result.indexOf("<"));
        }
        System.out.println(result);

        testCases--;
		}
  }
}

    For some reason I got errors.
