The problem is that they never describe what they want to do properly. If you search their OPs and replies, you'll notice that there's a communication issue. You may understand what they want from the title, but if you don't, there's nothing that is going to help you do.
~snip~
They drop two equations in which both of them should have the same result. Then, they conclude that r=r (?), s=s (?), z1 != z2 and they ask you to tell them how to gain x or k.
Then, there're the grammar mistakes. Even though that's not a reason for not helping someone, it makes it even harder to understand their process.
. It would make it so much easier & quicker to help instead of having to decipher what OP is actually trying to say as an additional step before actually thinking about the problem at hand.
We’d love to help you. To improve your chances of getting an answer, here are some tips:
Search, and research
Write a title that summarizes the specific problem
Introduce the problem before you post any code
Help others reproduce the problem
Include all relevant tags
Proof-read before posting!
Post the question and respond to feedback
Look for help asking for help
