LeetCode is an online platform offering coding challenges and interview preparation resources for software engineers and developers. The service provides coding and algorithmic problems, enabling users to practice coding and improve their problem-solving abilities.[1] LeetCode has gained popularity among job seekers and coding enthusiasts as a resource for technical interviews and coding competitions.[2][3][1][4]
Features
LeetCode offers both free and premium access options. While free users have access to a limited number of questions, premium users gain access to over 2500 algorithmically and user-generated questions. These questions are categorized into easy, medium, and hard difficulty levels, allowing users to select challenges based on their proficiency.[5] Users can also tag questions to facilitate searchability and provide assistance to others in finding relevant practice problems. The performance of users' solutions is evaluated based on response speed and solution efficiency, and is ranked against other submissions in the LeetCode database.[6]
LeetCode supports multiple programming languages, including Java, Python, JavaScript, and C.[7] Users can practice coding in their preferred language and utilize flashcards to study and reinforce their knowledge. The platform features forums where users can engage in discussions related to challenging problems, the interview process, and share their interview experiences for the benefit of the community. LeetCode also hosts weekly and bi-weekly contests, some of which were sponsored by companies like Amazon, Motorola, and Airtel.[8] Contestants have the opportunity to earn badges and "LeetCoin" rewards by successfully solving contest questions.

LeetCode was founded by Winston Tang in 2011 as an online platform catering to the needs of software engineers and programmers seeking coding challenges and interview preparation resources.
Recognizing the rising demand, LeetCode expanded its operations to China in 2018, aiming to serve the growing tech community in the country. In 2021, LeetCode secured its first round of funding, receiving a $10 million investment from Lightspeed China Partners, supporting Leetcode in its development and growth.

"To gear up for the assessments, many students practice their skills on LeetCode, a free test prep site that offers coding and algorithmic problems, along with detailed solutions. The site also offers premium services. For $35 a month, it gives members access to specific problems that companies like Amazon, Google and Microsoft previously used — and some continue to use — to assess applicants. To keep the questions up-to-date, the test prep service said, it regularly surveys members applying for tech positions."
