Copied Problem Red Blue Tree from CS Academy

Sir please tell me what is going to help me in landing interview at google. Sir you must be an employee there i guess

Even if one question was same have you seen the total number of ACs in that question…it is 192 for division 1 and 57 for division 2.
So do you think the competitors who were appearing the contest knew about this…for the worst case take 2-3% of them knew so these numbers didn’t even effect the competition at all I guess…and making a contest unrated on basis of this and with these numbers doesn’t make sense.
The motive of this post was to make aware that one of the question was same from CSacademy… right @ssrivastava990 ?

You said that I have bad googling skills. Actually it is not that my googling skills are bad, but I never search a problem during live contest :slight_smile:

Your googling skills are bad.
Thats not how you find a problem

In CSAcademy, n = 10^5 but here it’s 10^6. DFS should be able to do the job :thinking:

If someone copies the solution of that problem and submit it, then everyone below the ranking are effected, I am not asking for unrating the contest but there are many affected, and what about submissions before even the problem loaded ?

Just check out the runtime for the solution. It takes around .15 seconds to run on N <= 1e5 We have constraint here that \Sigma{N} <= 1e6. Assume that there is a case which tests this. It is bound to give a TLE.

Seeing your rank in long challenges and rank in short contests, it gives a rough idea how well you are at googling skills :slight_smile:
You had better not directly said “You have bad googling skills”, you could have used other appropriate words :slight_smile:

Here’s my submission
I copied it from CS academy, cause I knew this was a pretty standard problem. I think this was even asken in one quiz in my undergrad. Thankfully I have good Googling skills.

Either CSAcademy has weak testcases or there is something wrong with codechef.

PLEH !!

All those who saying to make the contest unrated, I don’t think anyone who solved the problem knew that it was copied.
