sktime gave a contest in codeforces and now he wants to discuss with other participants but he could not able to do that as he don't have any friends group who are interested in competitive programming. So he gave up on his desire and continued to participate in contests for quite a good amount of time with having a small amount of peer discussion.

Now he feels that peer discussion is THE most important thing that one should do after participating in a contest. So sktime with the help of shadar && vv1k designed a platform where competitive programmers can go and request other to join a room or can accept requests of others or can randomly pair with other participants by server for discussion.

Input

Your interest towards gaining knowledge is the only input here. You will be provided with the website link, go there and enjoy the platform which was build for you.

Output

comment "YES" if you enjoyed the platform, "NO" if you didn't.

You may print each letter in any case (for example, "YES", "Yes", "yes", and "yEs" will all be recognized as positive answers).

Example

Note

As of now it supports codeforces, codechef platforms. You will be seeing events in dashboard where can you can register for events, events here refer to discussion events of the contest so one should participate in respective contest to participate in its discussion event (as of now you can't see any events because there are no contests in codeforces and codechef). In future, instead of just contest discussion events we are planning for normal discussion events as well ( as per programmers interest 🙂 ). I hope you will like the platform and enjoy learning. It's still under testing so don't forget to give your value feedback. (mostly prefer using web browsers chrome,brave because I haven't tested in other browsers)

Please comment when do you want to have discussion for tomorrow's contest. Will let you know about event timmings before contest.
