Hey, HN!<p>I think that visualizing interview algorithms in that way can help lot of people to understand them, to form a "gut feeling" what's going on. What do you think?<p>This particular example, linked list reversal, is a "medium" interview question, but I've seen many times people failing it. When I solve this question by myself I always imagine this pointers, how they act and so on, and this visualization - it's what's going in my head. I really think that putting it on the list and animating it helps people to form long-term understanding.<p>What do you think?
