LeetCode Patch is a Chrome extension developed by disinuo. It falls under the category of Browsers and is listed as an Add-ons & Tools subcategory. This free extension is designed to help users hide the difficulty and acceptance rate of Leetcode problems, as well as the last executed input for failed submissions.

The main features of LeetCode Patch include the ability to hide the difficulty of problems on both the coding interface and the problem list page. After submitting a solution, if it is successful, the difficulty of the problem will be displayed, while the difficulty of recommended next challenges will be hidden. In the case of a failed submission, the extension can hide the last executed input, encouraging users to review their code logic instead of relying on the failed input.

LeetCode Patch is a simple and easy-to-use extension that aims to reduce the psychological pressure caused by visible difficulty levels while solving Leetcode problems. By hiding the difficulty and acceptance rate, users can focus on their coding skills without being influenced by preconceived notions. It also eliminates the delay in hiding the difficulty that some similar extensions have, providing a seamless user experience.

Please note that LeetCode Patch currently does not support the leetcode-cn website. With its helpful features, this extension is a handy tool for anyone looking to enjoy a stress-free coding experience on Leetcode.
