That’s a really clear explanation of the Reduced String problem! I like how you broke down the logic of repeatedly removing adjacent duplicates until the string can’t be reduced any further — it’s efficient and easy to follow. Using a stack definitely streamlines the process and keeps the solution clean. I was curious though, have you tried testing your code with very large strings or edge cases where almost all characters are the same? It would be interesting to see how it performs in those scenarios. While reading about similar problem-solving techniques, I came across some insightful resources like derma-roller and this one — both highlight how subtle refinements can make a big difference, much like optimizing an algorithm for better efficiency.
