Editorial Policy

Last updated: October 19, 2026

Editor and site owner: Nilesh Kumar.

This page explains the standards we follow when we plan, write, review and update content on LeetPrep, so that readers and search engines can understand how we work.

Our editorial principles

• Helpful first. Every article is written to solve a real learner’s problem, not to fill space.
• Original explanations. We write our own explanations and code. We do not copy articles, solutions or lists from other websites.
• Clarity over cleverness. We start with simple ideas and explain why an improved approach works.
• Honesty. We do not promise jobs, salaries or guaranteed results.

How articles are produced

Articles on this site are drafted with the help of AI writing tools. The site owner then reads, edits and corrects each piece before it is published, and every code example is run against test cases. We do not publish content that has not been checked.

Testing code

Python examples are run against sample inputs, including edge cases such as empty input and duplicates, before publication. If a solution has a limitation, such as recursion depth, we say so in the article.

Updates and corrections

If you find a mistake, please tell us on the contact page. We review every report and correct confirmed errors as soon as possible. Articles show the date they were last updated when the change is significant.

Advertising disclosure

This website displays advertisements served by Google AdSense and possibly other partners. Ads are clearly labelled and do not affect our editorial decisions. We do not publish paid reviews or sponsored articles that are presented as independent advice.

External links and trademarks

We link to outside sources only when they help the reader. Names such as LeetCode belong to their owners. We use them to identify practice problems, and we are not affiliated with or endorsed by them.
