I am new in Codeforces in that case I have some questions. In Round Div(2 , 3 , 4) contests I saw button hack. How does it work and how to hack? Should I hack another codes or not? But how I understood I should to give some hard tests to another participant's code. Is that enough? Write all you know pls?!

Hi, I'm new here too, but I heard hacking is like you can submit a test case that meets the constraints of the question to hack someone whom you think his/her solution cannot pass the test case (e.g. TLE / Memory Limit Exceeded). And I suppose if the hack is successful you can gain extra points, also you need to lock your accepted solution before you can hack anyone so that you cannot resubmit in-comp anymore. Not too sure tho.
it's correct
Understandable, thanks!
