Wow, @ericandryan, day 220! That's some serious dedication to coding with your child! I'm absolutely loving this series, and this post on finding the intersection of two arrays using the two-pointer algorithm is fantastic. The clear explanations and visualizations make a potentially complex topic so accessible, especially for young learners.

The way you break down the logic and showcase the code snippets is brilliant. It's inspiring to see you fostering problem-solving skills in such an engaging way. Keep up the amazing work! I'm sure many parents and educators on Steemit will find this valuable. What other algorithms are you planning to tackle next? I'm eager to see what you and your child explore!
