I've started a little Vancouver group to facilitate excellence in CS fundamentals. Ask questions and join in on our weekly meetups where we discuss time and space complexities, common and less common data structures, popular algorithms, and walk through leetcode and hackerrank challenges.
1337 Practice gestures to the realization of special knowledge through the application of computer science principles and theory -> practice/praxis/study.
This is a growing group, and eager to find active participants. Everyone welcome, from new CS students to old-timer software developers and hobbyists.
