Did anyone work on KMP algorithm? Plz explain it

[lul123]

I am learning different pattern searching algorithms. I am kind of stuck with KMP algorithm. I am not able to understand how the time complexity is O(m+n). I think I am not fully getting how the steps work for this algorithm. I already tried multiple resources. It would be helpful if someone who worked on it can explain it in easier terms.

Everything doesn't use the KMP algorithm.

Typically Everything searches are small, so KMP will offer no real-world performance increase.

Thanks @void.
I found another article which was a bit simpler to understand https://www.w3spot.com/2020/07/kmp-algo ... glish.html, but it doesn't have code implementation like the one you shared.
