CS50 Fall 2025 - Lecture 5 - Data Structures (live, unedited)

In this lecture, the speaker discusses data structures in C programming, focusing on trade-offs between efficiency and memory usage. The lecture covers abstract data types like stacks and queues, illustrating their properties with real-world examples. It delves into the implementation of arrays, linked lists, binary search trees, and hash tables, explaining the advantages and disadvantages of each in terms of speed, memory allocation, and dynamic resizing. The lecture emphasizes the importance of choosing the right data structure based on specific problem requirements, highlighting the trade-offs between time and space complexity.
