I just wonder can codeforces add the compile and test option to the problems ... (i.e. before submitting the user can compile his solution and test it against the sample test) ?
please let me know if this feature is already there. Thanks.
UPD : I know that there exist some programs for automatic testing ... but i would like if this feature is in the website itself

There's no such feature in Codeforces.
But you can use automatic tester dy dj3500 — Hightail.
thanks for replying ... actually i already have hightail but i like the idea of having such feature in the website itself ... not a third party program
What is the difference?
if it's in the website the judge will do the testing for you so you can make sure the sample test cases is correct and do it fast .... other programs just make that task harder by some difficulties like contest time i.e. you have to wait until contest time to add the contest problems (or you may make a schedule) .... another problem is the precision error and that may differ from one problem to another.
also if there is a problem with "If there are several possible answers, output any of them." how can a program determine if your program output is correct ?
