Notes on the things I had to understand properly before I could use them — the patterns behind the algorithms, and the switches underneath the code.
Discover how billions of tiny switches (transistors) power every line of code you write. Journey from binary switches to software, exploring the layers of abstraction that make modern computing possible.
Learn how to use the Sliding Window pattern in JavaScript to optimize your algorithms from O(N²) to O(N) time complexity. Perfect for finding subarrays, substrings, and consecutive sequences efficiently.
Learn how to use the Two Pointers pattern in JavaScript to optimize your algorithms from O(N²) to O(N) time complexity. Perfect for solving problems with sorted arrays and strings efficiently.
Learn how to use the Frequency Counter pattern in JavaScript to optimize your algorithms from O(N²) to O(N) time complexity. Perfect for comparing arrays and strings efficiently.
