CF 103347G - Ophelia's Flowers

Let $rs,dots,r0$ satisfy $$t = rs + cdots + r1 + r0,qquad 0 le rj le mj quad (s ge j ge 0).$$ Write $$Mj = sum{i=0}^j mi,qquad Tj = t - sum{i=j+1}^s ri,$$ so $Tj$ is the remaining sum to be distributed among indices $0,dots,j$ after fixing $rs,dots,r{j+1}$.

CF 103347J - Rosencrantz and Guildenstern

The problem starts with a modular arithmetic condition involving three fixed values and a variable exponent. We are given a prime modulus $p$, two residues $x$ and $y$ in the range $1$ to $p-1$, and a very large upper bound $a$.

CF 103347B - Ophelia's Sadness

Let a 4-note chord be a 4-combination $c4c3c2c1$ with $n c4 c3 c2 c1 ge 0.$ A single “adjacent-key move” replaces exactly one $cj$ by $cj pm 1$ while preserving strict inequalities. Write the standard gap variables from (10) in Section 7.2.1.

CF 103347I - Witches Cauldron II

The problem statement is missing from your prompt, so I don’t have the actual task definition, constraints, or required output format for Codeforces 103347I - Witches Cauldron II.

CF 103347H - Ophelia's Madness

The problem statement is not included in the prompt, so there is no way to reconstruct the task, constraints, or required output. Without that, any “editorial” would be purely speculative and would not satisfy correctness or usefulness requirements.

CF 103347F - Playwrite

The problem statement is missing from the prompt, so there isn’t enough information to produce a correct Codeforces-style editorial. Right now we only know the title “103347F - Playwrite”, but we don’t have the actual input format, output requirements, or the core task.

CF 103347E - Globe Line

The problem statement for Codeforces 103347E - Globe Line is not included in your message, so I can’t reliably reconstruct the task or write a correct editorial. For a Codeforces editorial, the exact rules, constraints, and input/output behavior matter heavily.

CF 103347D - Witches Cauldron I

I’m missing the actual problem content for Codeforces 103347D - Witches Cauldron I. The prompt only includes an empty “Problem Statement / Input / Output” section, so there’s nothing to analyze or derive an algorithm from.

CF 103347C - Juliet's Garden

We are given a circular garden with $n$ flower beds labeled from $1$ to $n$, where after $n$ we wrap back to $1$. Juliet starts at bed $1$. Time progresses in discrete minutes, and during minute $i$, her movement step size is exactly $i$, increasing every minute.

CF 103347A - Ophelia's Happiness

I’m missing the actual problem statement (input/output description and constraints). Without that, any “editorial” would just be guessing the task, which would defeat the purpose of a correct Codeforces solution write-up.
