We get different amount of points by doing each activity each day. I think it will work by doing RMQ, but how you maintain the |h_i-h_j| is the problem.

You will have access to copy any solution and test it locally. 素のPythonで書くならこうですね。, 一般にnumpyは配列に対する一括処理を得意とします。本問では$dp[i]$を逐次計算するのではなく、連続部分列 $dp[i:i+K]$に対する処理を、$i$を$1$から$N$まで動かしつつ実行していく処理に変更します。, 例えば先の例において、$dp[3]$の値が確定してから操作$\text{chmin}(dp[6],|H[6] - H[3]| + dp[3])$がなされるまでには、ある程度間があいています。これを、$dp[3]$が求まってすぐに操作$\text{chmin}(dp[6],|H[6] - H[3]| + dp[3])$を行うようなアルゴリズムに変更しても答えは変わりません。 Maybe you want to go into more detail since you are targeting beginners, but hopefully that will help. There is also a special recognition prize from the ICPC: ICPC- experience, an invitation to the Moscow World Finals 2021, all-inclusive on-site (hotel, meals, ceremonies, and swag, are included; visa, flights, transportation to the contest location is not).

We will announce the scoring distribution shortly. On Nov/02/2020 17:35 (Moscow time) we invite everyone to participate in Codeforces Round #681 (Div. 205 successful hacks and 712 unsuccessful hacks were made in total! The Kotlin Heroes 5: ICPC Round competition will be hosted on the Codeforces platform on Nov/12/2020 17:35 (Moscow time).

Regional qualifying contests are held in January. We hope that you will enjoy them as much as we did :).

I'm writing this post keeping beginners in mind. Each division will have 5-6 problems. You’ll be able to ask the team all you’ve ever wanted to know about Kotlin, IDEs, and tools via chat or during the Q&A sessions with the presenters. Is it bad practice to see failed test cases while practicing? You are only allowed to use Kotlin to solve these problems. Teams of three to four youth evaluate and identify cuts of beef, pork, and lamb.

We’d like to thank for the huge help in preparing and testing the problems MikeMirzayanov, ecnerwala, Egor, hos.lyric, yosupo, lperovskaya, Stepavly, Supermagzzz, HIR180, qwerty787788. We are given three types of activities.

Technocup is a major olympiad for Russian-speaking high-school students, so if you fall into this category, please register at Technocup 2021 website and take part in the Elimination Round. Auto comment: topic has been updated by algorist_ (previous revision, new revision, compare). If two participants solved the same number of problems and scored the same penalty, then those of them who had previously made the last successful submission will be given an advantage in the distribution of prizes and gifts.

The Elimination Round will feature 6 problems, preliminary costs are 500 — 1000 — 1500 — 2000 — 2250 — 3000.

Meet IT family members worked hard over the last few months to provide you with our favourite challenges we came up with. We build a community where people learn together, motivate and help each other. I wanted to, with the help of this community, create a collection of about 25 — 30 advanced DP problems, which would have a structure similar to the problems of AtCoder's Educational DP Contest (classical problems; simple, straight-forward statements) but more harder. Regional qualifying contests are held in April and May. Register and enjoy the contests!
