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.
HackerRank's programming challenges can be solved in a variety of programming languages (including Java, C++, PHP, Python, SQL, and JavaScript) and span multiple computer science domains. [ 2 ] HackerRank categorizes most of their programming challenges into a number of core computer science domains, [ 3 ] including database management ...
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 execution speed and memory usage , and is ranked against other submissions in the LeetCode database.

The sister site softwareengineering.stackexchange.com is intended to be a venue for broader queries, e.g. general questions about software development. [30] Closing questions is a main differentiation from other Q&A sites like Yahoo! Answers and a way to prevent low quality questions.
Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
Range minimum query reduced to the lowest common ancestor problem.. Given an array A[1 … n] of n objects taken from a totally ordered set, such as integers, the range minimum query RMQ A (l,r) =arg min A[k] (with 1 ≤ l ≤ k ≤ r ≤ n) returns the position of the minimal element in the specified sub-array A[l …
In Java and Python 3.11+, [40] quantifiers may be made possessive by appending a plus sign, which disables backing off (in a backtracking engine), even if doing so would allow the overall match to succeed: [41] While the regex ".*" applied to the string "Ganymede," he continued, "is the largest moon in the Solar System."
