Visual Course on Data Structures and Algorithms
freeCodeCamp News
EDITOR BRIEF
A new freeCodeCamp.org YouTube course taught by Sumit Saha explains data structures and algorithms using real-world analogies. It covers arrays, linked lists, stacks, queues, hash tables, trees, graphs, searching and sorting, and core methods like recursion, greedy techniques, divide-and-conquer, and dynamic programming. The goal is to build an intuitive mental model of how data is stored and optimized.
INSIGHTS
This is useful because DSA becomes easier once you can connect the idea to a familiar example. A good next step is to watch the course and practice each structure by drawing how it works or coding a small example.
