"Thanks JAY19 for the info! Excited to participate in CodeChef Starters 175(Rated upto 5 stars). Looking forward to the challenges. Good luck to everyone!"
Why not a CF round anymore like ICM, Technex'18 ?
Skill isu and queue is too long..
Will this contest be ICPC style (penalty for WA) or usual codechef starters ?
The contest is usual codechef starters.
I got the following while trying to register on Unstop:
You are not eligible as your profile details does not match the following eligibility criteria:
But I haven't seen any eligibility limitations (like that it's for students only) anywhere
it is mentioned here if you missed it by any chance.
I meant in the announcement here/Technex website/poster on Google Drive. That one on Unstop I saw after receiving an error, so was curious if it's not a mistake. Thanks for confirming!
Multiplexer got over 40 AC in div2 in the last 2 minutes. Indians are so smart wow.
If I knew Inclusion-Exclusion Principle better I would also be smart but got AC now so me not smart XD.
More simpler solution using kadane's algorithm Link
Div1 B similar to 1082E - Increasing Frequency
MXFREQ is a good one.
