cscrapper

cscrapper is a tool designed to scrape problem statements from popular competitive programming platforms like CodeChef and CodeForces. It provides a unified interface to fetch problem details, including the problem statement, input format, and constraints.

Features

• Multi-Platform Support: Supports scraping from both CodeChef and CodeForces.
• Unified Interface: Provides a single function to fetch problem statements from different platforms.
• Error Handling: Gracefully handles errors and provides meaningful error messages.

Getting Started

Prerequisites

Ensure you have Rust installed on your machine. You can install Rust using rustup.

Installation

Add cscrapper as a dependency in your Cargo.toml:

[dependencies]
cscrapper = "0.1" 

Usage

Here’s a complete example demonstrating how to use the cscrapper module:

use cscrapper::{get_problem_statement, CodePlatform};

#[tokio::main]
async fn main() {
    // Fetch a problem statement from CodeChef
    let result = get_problem_statement(CodePlatform::CodeChef("NONNEGPROD")).await;
    match result {
        Ok(response) => {
            println!("Statement: {}", response.statement);
            println!("Input Format: {}", response.input_format);
            println!("Constraints: {}", response.constraints);
        }
        Err(e) => eprintln!("Error fetching problem statement: {:?}", e),
    }

    // Fetch a problem statement from CodeForces
    let result = get_problem_statement(CodePlatform::CodeForces("1331", "B"));
    match result {
        Ok(response) => {
            println!("Statement: {}", response.statement);
            println!("Input Format: {}", response.input_format);
            println!("Constraints: {}", response.constraints);
        }
        Err(e) => eprintln!("Error fetching problem statement: {:?}", e),
    }
}

Supported Platforms

• CodeChef: Fetch problem statements using the problem code.
• CodeForces: Fetch problem statements using the contest ID and problem code.
