Can we use LeetCode offline?

No, you cannot use LeetCode offline. LeetCode requires an active internet connection to access its problems, submit solutions, and interact with the platform's coding environment.

The LeetCode app and the website rely on a live connection for:

• Submitting code: Your solutions are evaluated on LeetCode's servers.
• Accessing problems: Problem sets, test cases, and discussion forums are all stored online.
• Leaderboards and Contests: Participating in real-time contests and rankings requires continuous internet access.

For offline practice, you might consider downloading problems from LeetCode and solving them on your local machine or using coding books like Cracking the Coding Interview.
