Sometimes it happens that I solve the problem and I have tests, but I can't find problem on the internet. So I need a tester that can test my solution on tests. I tried to find it on the internet, but I can't. I will appreciate if you give me such program. Thank you!
I use Hightail for contests (http://codeforces.net/blog/entry/13141) and it works really well. It's open source -- maybe you could adapt it to read files?
I also use Hightail for contests. It is really cool program. But it is a problem in it. Hightail can't work without contest(or task in CodeForces, CodeChef etc). And I want a program that will work with tests on my computer. Just tests and execution file. And it checks and I get AC, WA...
A simple bash script would suffice. Something like this:
(Obviously if the answer is not unique, you'll have to replace diff with a manually implemented checker.)
Alternatively, you could use my caide software which has other features in addition to tester.
