While browsing the web for for good videos to help me land a cool job at high profile tech firm, I came across this series from an Indian university.
Lecture – 16 Disk Based Data Structures
You should be able to easily find the other videos in the series through this one. Generally the subjects that are covered relate to data structures and algorithms:
- Trees (Red-Black, B, AVL)
The videos are very practical and relate the data structures to scenarios where they would be used, like for bank transactions etc.
