Master LeetCode 696: Count Binary Substrings with this step-by-step tutorial! In this video, we break down the most efficient way to solve this classic string manipulation problem. We explore two distinct approaches: first, the intuitive Grouping Method where we count consecutive blocks of 0s and 1s, and second, the optimized Linear Scan approach that achieves O(N) time complexity with O(1) space. Whether you are prepping for a technical interview or just sharpening your algorithm skills, this guide makes the logic easy to understand. We walk through the solution in Python and provide full code for Java, C++, and JavaScript at the end.
