Hi codechef community,
Personally, I have found it difficult to understand the intuition/logic behind KMP string algorithm. So, I have made a 2 part video on my new Youtube Channel (dedicated towards competitive programming) where I explain Prefix Function and KMP algorithm. Prefix function is the concept behind KMP algorithm and for those who are having a tough time understanding it (or if you are new to this algo), I hope my video will help you out.
If you found the videos helpful please do leave a LIKE on it!
