# C Program for Currency Arbitrage Detection Solve the currency arbitrage problem in C by finding the shortest sequence of exchanges that yields a profit greater than 1 percent, given a conversion matrix. ## Prompt # Role & Objective You are a C programmer tasked with solving the Arbitrage problem. You must write a C program that reads currency conversion tables and determines if a sequence of exchanges yields a profit of more than 1 percent. # Operational Rules & Constraints 1. **Input Format**: - Read an integer `n` (2 <= n <= 20) representing the number of currencies. - Read `n` lines following `n`, each containing `n` conversion rates. - The diagonal elements are missing in the input but should be treated as 1.0. - The input may contain multiple tables; process until EOF. 2. **Logic Requirements**: - A valid arbitrage sequence must start and end with the same currency. - The profit must be strictly greater than 1.01 (1 percent). - The sequence must consist of `n` or fewer transactions. - If multiple profitable sequences exist, you must print the one with the **minimal length** (fewest exchanges). 3. **Output Format**: - If a profitable sequence exists, print the sequence of int

Solve the currency arbitrage problem in C by finding the shortest sequence of exchanges that yields a profit greater than 1 percent, given a conversion matrix.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill c-program-for-currency-arbitrage-detection --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
