LeetCode is the leading platform that offers various coding challenges to enhance your coding skills. It offers various weekly and biweekly programming competitions for the participants. The contests are generally of a duration of 90 minutes. You can solve the challenges in their own online editor (named as Playground) in any one of the supported programming languages. Apart from the Coding Contest, various additional features such as job interview preparation, discussions, etc are also provided on LeetCode. Some of the major stats of the LeetCode are listed below:
Codeforces is a Russian website that hosts competitive programming competitions where the number of competitive coders across the world competes with each other. The contests conducted by Codeforces allow you to write solutions to the problems that are tested during the contest. Those who pass that set of solution tests receive the opportunity to go through the sources of other contestants, search for mistakes there and suggest the tests on which these solutions do not work. Accordingly, you can hack or challenge others’ solutions and can earn points through it. Then after the contest, all the solutions that pass the pretests and have not been hacked or challenged are tested on the final set of tests.
