GenGen CF RMJ 是一款基于用户脚本（Userscript）的浏览器增强工具，主要面向参与信息学竞赛（OI）的用户。其核心功能是将 Codeforces（CF）平台的部分功能“嵌入”到洛谷（Luogu）网站中，实现无缝切换与操作。用户可以在洛谷界面上直接查看、提交和评测 Codeforces 的题目，而无需跳转到 Codeforces 官网。这不仅提升了使用体验，也简化了多平台切换的繁琐流程。

此外，该脚本还致力于优化洛谷与 Codeforces 之间的数据同步、评测记录展示、题目链接整合等功能，为 OI 选手提供更高效、统一的训练环境。

GenGen CF RMJ is a browser-based userscript tool designed primarily for competitive programming (OI) participants. Its core functionality is to "embed" parts of the Codeforces (CF) platform directly into the Luogu website, enabling seamless interaction between the two platforms. Users can view, submit, and check the evaluation results of Codeforces problems directly within the Luogu interface—without needing to navigate to the Codeforces website. This significantly enhances user experience and eliminates the hassle of switching between multiple platforms.

Additionally, the script aims to improve data synchronization, display submission records, and integrate problem links between Luogu and Codeforces, offering OIers a more efficient and unified training environment.
