please anyone response.may god bless him and make the best coder in the world.tried all self made test cases.stck for long time

I didn't read your code and didn't submit the problem, but here is a hint:

Every statement is either true or false.

Let's say we have something like this on statement number X:

X: Statement Y is true

So, either both statements are true, or both statements are false, in symbols:

(X and Y) or (¬X and ¬Y) = (X or ¬X) and (X or ¬Y) and (Y or ¬X) and (Y or ¬Y) = (X or ¬Y) and (Y or ¬X)

The same reasoning can be applied do statements X of type

X: Statement Y is false

If you need more hints just ask.
