Description

Do Not Be Confused! There is no input and output description for this problem. I wrote it, but I think it is too easy for you all. So I encrypted it.

The procedure is like this：

1, I wrote the description，stored it in a text file namely a.txt.

2, Then I wrote a program to read all content in file a.txt.

3, For every character(ASCII), after doing an operator xor with 1, I stored it into another file b.txt sequently.

4, The content of b.txt is "Bnofsutmuhnor !Xnt!iwd!fnu!uid!jdx !On!hoqtu-!xnt!ktru!odde!un!ntuqtu!#Vdmbnld!un![KTU!@BL.HBQB!Udl #!vhuintu!uid!ptnu`uhno/" without the quotation.

so...if you want to solve this problem, just decrypt it...
