Hello, Codeforces!!


Guys, how do you stress-test your solutions? I know at least three possible ways to do it.

1)Right in your solution file
Write second stress-solution ( definitly correct, but quite slow ), generator, checker, ect. right in your solution file as functions and call functions from main.
I personally use this variant, it is fast and convinient. But there is one problem using this method.. When you have your solution fixed, you have to comment all your stress-code.. I have a trick: just make copy of your file before adding stress-testing functions and add them in your second file, after debugging you will have to just fix jour solution in the first file.

2)Python script
Some people write Python scripts to stress their solutions. You have two programs: solution with bug and stress-solution. So you can just generate tests, lauch your solutions, check answers, etc. from Python script.

3)Bash or maybe Bat scripts
Method is idiologically similar to the 2)Python script, but you write bash/bat scripts.


Which method do you use? Or maybe you have your own techniques, share in comments.
