See
[my config](https://github.com/barrettruth/dots/blob/main/.config/nvim/lua/plugins/cp.lua)
for the setup in the video shown above.
## Motivation
I could not find a neovim-centric, efficient, dependency-free, flexible, and
easily customizable competitive programming workflow that "just works"--so I
made it myself. I conferenced with top competitive programmers at Carnegie
Mellon Univerity and the University of Virginia and covered their (and my) pain
points:
- Scraping: contests are automatically loaded asynchronously
- Test Case Management: test case editor (`:CP edit`)
- UI: both `run` and `panel` layouts cover common formats
- Extensibility: snippet plugins, compilation, etc. are left to the programmer
See [my config](https://github.com/barrett-ruth/dots/blob/main/nvim/lua/plugins/cp.lua) for a relatively advanced setup.

<h3>問題文</h3>
<p>
もうすぐ E869120 君と square1001 君の
<var>16</var> 才の誕生日が来る.<br />
そこで, AtCoder 王国の高橋君は, 円形のケーキ
<var>1</var> 個に放射状に切れ目を入れ
<var>16</var> 等分したものを, 彼らにプレゼントした.
</p>
<p>
E869120 君はそのうち <var>A</var> 切れ、square1001 君は
<var>B</var> 切れを食べようとした.<br />
しかし, ケーキと一緒についていた紙を見ると,
「同じ人が隣り合う
<var>2</var>
切れのケーキを両方取ってはならない」と書かれていた.
</p>
<p>
さて、彼らは紙に書かれたことを守って、<var>2</var>
人とも食べたい数のケーキを取ることができるだろうか？

<h3>Problem Statement</h3>
<p>
E869120's and square1001's <var>16</var>-th birthday is
coming soon.<br />
Takahashi from AtCoder Kingdom gave them a round cake
cut into <var>16</var> equal fan-shaped pieces.
</p>
<p>
E869120 and square1001 were just about to eat
<var>A</var> and <var>B</var> of those pieces,
respectively,<br />
when they found a note attached to the cake saying that
"the same person should not take two adjacent pieces of
cake".
</p>
<p>
Can both of them obey the instruction in the note and
take desired numbers of pieces of cake?
</p>

<h3>Problem Statement</h3>
<p>
Today, the memorable AtCoder Beginner Contest 100 takes
place. On this occasion, Takahashi would like to give an
integer to Ringo.<br />
As the name of the contest is AtCoder Beginner Contest
100, Ringo would be happy if he is given a positive
integer that can be divided by <var>100</var>
<strong>exactly</strong> <var>D</var> times.
</p>
<p>
Find the <var>N</var>-th smallest integer that would
make Ringo happy.

<h3>問題文</h3>
<p>
AtCoder Beginner Contest 100 の開催にともなって, AtCoder
社では長さ <var>N</var> の数列 <var>a = </var>{<var
>a_1, a_2, a_3, ..., a_N</var
>} が飾られることになった. <br />
社員のすぬけ君は, この数列で遊んでみようと思った.
</p>
<p>
具体的には,
以下の操作をできるだけ多くの回数繰り返そうと思った.
</p>
<pre><var>1 \leq i \leq N</var> を満たす全ての <var>i</var> に対して, それぞれ「<var>a_i</var> の値を <var>2</var> で割る」「<var>a_i</var> の値を <var>3</var> 倍する」のどちらかを行う.
ただし, 全ての <var>i</var> に対して <var>3</var> 倍することはできず, 操作後の <var>a_i</var> の値は整数でなければならない.
</pre>
<p>最大で何回の操作が可能か, 求めなさい.</p>

<ul>
<li>
最初に, <var>a_1</var> を <var>3</var> 倍し,
<var>a_2</var> を <var>3</var> 倍し, <var>a_3</var> を
<var>2</var> で割る. すると数列は

次に, <var>a_1</var> を <var>3</var> 倍し,
<var>a_2</var> を <var>2</var> で割り,
<var>a_3</var> を <var>3</var> 倍する. すると数列は

<h3>Problem Statement</h3>
<p>
As AtCoder Beginner Contest 100 is taking place, the
office of AtCoder, Inc. is decorated with a sequence of
length <var>N</var>, <var>a = </var>{<var
>a_1, a_2, a_3, ..., a_N</var
>}.<br />
Snuke, an employee, would like to play with this
sequence.
</p>
<p>
Specifically, he would like to repeat the following
operation as many times as possible:
</p>
<pre>For every <var>i</var> satisfying <var>1 \leq i \leq N</var>, perform one of the following: &quot;divide <var>a_i</var> by <var>2</var>&quot; and &quot;multiply <var>a_i</var> by <var>3</var>&quot;.
Here, choosing &quot;multiply <var>a_i</var> by <var>3</var>&quot; for every <var>i</var> is not allowed, and the value of <var>a_i</var> after the operation must be an integer.
</pre>
<p>At most how many operations can be performed?</p>
</section>
</div>
<div class="part">
<section>
<h3>Constraints</h3>
<ul>
<li>
<var>N</var> is an integer between <var>1</var> and
<var>10 \ 000</var> (inclusive).
</li>
<li>
<var>a_i</var> is an integer between <var>1</var> and
<var>1 \ 000 \ 000 \ 000</var> (inclusive).
</li>
</ul>

<p>
The sequence is initially <var>{5, 2, 4}</var>. Three
operations can be performed as follows:
</p>
<ul>
<li>
First, multiply <var>a_1</var> by <var>3</var>,
multiply <var>a_2</var> by <var>3</var> and divide
<var>a_3</var> by <var>2</var>. The sequence is now
<var>{15, 6, 2}</var>.
</li>
<li>
Next, multiply <var>a_1</var> by <var>3</var>, divide
<var>a_2</var> by <var>2</var> and multiply
<var>a_3</var> by <var>3</var>. The sequence is now
<var>{45, 3, 6}</var>.
</li>
<li>
Finally, multiply <var>a_1</var> by <var>3</var>,
multiply <var>a_2</var> by <var>3</var> and divide
<var>a_3</var> by <var>2</var>. The sequence is now
<var>{135, 9, 3}</var>.
</li>

Also, we believe that it is alright to refer to tutorials, books, and other materials, learn a concept, and then apply the same to solve a problem during a contest. But it is <strong>not alright to copy other people's solutions or seek other people's help to solve a problem. <\/strong>All the participants are expected to abide to <a class=\"button blue\" href=\"..\/codeofconduct\">CodeChef's Code Of Conduct<\/a>.<\/p>\n<h4>Rules and Regulations:<\/h4>\n<ul>\n<li>This is an IOI-style contest. This means that the problems will be partially graded. You will get the score for passing certain test data.<\/li>\n<li>The details of the failed test cases will also be visible on your solution page.<\/li>\n<li>You can submit solutions as many times as you'd like, there are no penalties for incorrect submissions. Only your best correct submission will be considered.<\/li>\n<li>Those who achieve the score first will be placed higher in the ranklist in case of a tie.<\/li>\n<li><strong>We have removed all the Institutions that we could not identify from our database. We request you to update your institutions once again by going to your profile page.<\/strong><\/li>\n<li>You can also send in your queries in an email to <a href=\"mailto:help@codechef.com\" target=\"_blank\" rel=\"noreferrer noopener\">help@codechef.com<\/a>, during the contest.<\/li>\n<li>Please do not discuss strategy, suggestions, or tips in the comments during a live contest. Posting questions clarifying the problem statement is ok.

Please make sure to remove everything here before publishing your problem.\n\n- Codechef uses markdown for its problem statements. Markdown syntax can be found [here](https:\/\/github.com\/showdownjs\/showdown\/wiki\/Showdown's-Markdown-syntax). Note the `[text](link)` syntax to insert a hyperlink.\n- Codechef also uses $\\LaTeX$ to render mathematical expressions, and you are advised to make liberal use of it to make your statement look good.\n- Text can be made **bold** or *italicized*.\n- **Do not** use HTML tags (p, ul, li, pre, br, ...) in the statement.\n- To insert an image, first upload it to an online hosting service (for an official contest, ask a Codechef admin to do this for you \u2014 this is important) and then use the following syntax: `![alt text](link-to-image)`.\n- If your problem doesn't contain subtasks, ensure that the Subtasks section below is disabled and **all content is deleted from it**.\n\nIf you face any issues, either contact a Codechef admin directly or send us an email at help@codechef.com.\n\nBelow is an example problem statement that uses some of the above-mentioned features.\n\n---------\n\nChef has a simple undirected graph $G$ with $N$ vertices and $M$ edges.

<p>
Consider an algorithm that takes as input a positive integer
<span class="math math-inline">n</span>. If
<span class="math math-inline">n</span> is even, the algorithm
divides it by two, and if
<span class="math math-inline">n</span> is odd, the algorithm
multiplies it by three and adds one. The algorithm repeats this,
until <span class="math math-inline">n</span> is one. For example,
the sequence for <span class="math math-inline">n=3</span> is as
follows:
<span class="math math-display">
3 \rightarrow 10 \rightarrow 5 \rightarrow 16 \rightarrow 8
\rightarrow 4 \rightarrow 2 \rightarrow 1</span
>
Your task is to simulate the execution of the algorithm for a
given value of <span class="math math-inline">n</span>.
</p>
<h1 id="input">Input</h1>
<p>
The only input line contains an integer
<span class="math math-inline">n</span>.
</p>
<h1 id="output">Output</h1>
<p>
Print a line that contains all values of
<span class="math math-inline">n</span> during the algorithm.
