A Final Note We highly recommend reading all the problems, as the difficulty might be subjective. We hope you enjoy the problems as much as we enjoyed creating them.
Good luck, have fun, and see you on the leaderboard!
Kindly recheck the test cases for Problem E, the expected output contradicts the explanation results.
Checking, give me a min
You're correct, would fix that in 15 mins, thanks for letting me know!
It looks like only the solution for B is uploaded under the contest materials. I'm guessing you meant to upload all of them?
Hello, the solution pdf will be shared in the community group, and here shortly, after the leaderboard results get verified :)
