Great video, thanks a lot. It 's a bit strange that you don't have more views.

Great video, guys! I like the examples of application of this two-pointer approach. They showed how to optimally solve a problem that I haven't thought about. Btw, in the future, perhaps you could consider making videos about math related topic such as: Checking if number is prime, counting gcd (greatest common divisor), lcm (lowest common multiple). After all algorithms and computer science are related to math :D

Glad it was helpful! And (between us) we are actually working on a Math Series (but it is in the far future)! Stay Tuned :)

@@geekific "between us" nice old joke:)) Wished to ask what are your current and upcoming plans in terms of video topics? Going to cover most videos on your channel but my urgent point is Leetcode and related techniques.
