It is absolutely meaningless text, isn't it?Solution:
1. View-source in page, I think it just a pattern in <em></em> tag and get some word like "flag is not this line but you think right way"
2. View-source again and look at <e></e> tag, It have <e>one</e> and <e>zero</e>, yeah it is binary!!
3. Write a python script to solve this below.
Good job. :D
