In this build, I added the problem fetcher and the contest fetcher to Competitive Programming Helper. Both systems connect with platforms like Codeforces and AtCoder. Without these features, the app was just a static text editor that required copying and pasting test cases manually. Fetching data directly turns it into an automated workflow tool.functionality-wise, the problem fetcher takes a problem ID from Codeforces, extracts the sample test cases, and runs the user’s local code against them to check the output. At the same time, the contest fetcher uses a web scraper to pull upcoming competition schedules from both Codeforces and AtCoder into a single list.Together, these features build out the core data pipeline for the app, handling local test execution and schedule tracking in one place.
