Hey! Just one additional info, if you do the two pointers swap in the same array, you will not need an extra space, so the space complexity will be O(1)

Hi nikhil, can you come up with one roadmap video for all your uploaded videos. Probably your videos are shuffelled.

[@nikhilgawde]

It will be really helpful!

[@nikoo28]

Have you guys looked at the available playlists on my channel. If they aren’t helpful, let me know…I will work on creating a better roadmap

[@rudreshcm4172]

Yeah nikhil, you uploaded videos topic wise too like graph playlist , trees etc. but for leetcode videos , are shuffelled. So may be you can bring one roadmap video specifically for your channel to best utilize
