HackerRank categorizes most of their programming challenges into a number of core computer science domains, [3] including database management, mathematics, and artificial intelligence. When a programmer submits a solution to a programming challenge, their submission is scored on the accuracy of their output.
HackerRank: HackerRank offers programming problems in different domains of Computer Science. It also hosts annual Codesprints which help connect the coders and Silicon Valley startups. LeetCode: LeetCode has over 2,300 questions covering many different programming concepts and offers weekly and bi-weekly contests.
This article is a list of notable unsolved problems in computer science. A problem in computer science is considered unsolved when no solution is known or when experts in the field disagree about proposed solutions.
While free users have access to a limited number of questions, premium users gain access to additional questions previously used in interviews at large tech companies. [1] The performance of users' solutions is evaluated based on response speed and solution efficiency, and is ranked against other submissions in the LeetCode database.

Meta Hacker Cup (formerly known as Facebook Hacker Cup) is an annual international programming competition hosted and administered by Meta Platforms.The competition began in 2011 as a means to identify top engineering talent for potential employment at Meta Platforms. [2]
Determining if a context-free grammar generates all possible strings, or if it is ambiguous. Given two context-free grammars, determining whether they generate the same set of strings, or whether one generates a subset of the strings generated by the other, or whether there is any string at all that both generate.
Queues are common in computer programs, where they are implemented as data structures coupled with access routines, as an abstract data structure or in object-oriented languages as classes. A queue has two ends, the top, which is the only position at which the push operation may occur, and the bottom, which is the only position at which the pop ...
