An excellent [Algorithms] playlist from Abdul Bari. As this playlist is geared toward a slightly more advanced course than CSC205, some of the material is far more in depth than required for CSC205. However, for topics you are struggling to understand, or to get a deeper understanding of some of the topics I would recommend you look for a corresponding video in this playlist.
