Great video. A dry run with an example string through the code would be nice as well. Helps visualize how the string is being processed

I really like this video. Central programming problems have been picked and explained almost perfectly. The content is well prepared and presented similarly. This channel should serve as a nodal point for those who are at intermediate level of programming.
