Trying to Understand KMP Algorithm

I am trying to understand KMP (Knuth-Morris-Pratt) algorithm for pattern matching. I read some articles online but having trouble to understand the logic. I want something which is as simple as possible, no mathematical terms. I read from website like GeeksForGeeks & TutorialsPoint etc. Still I am having doubts. If someone can help me with alternative articles I will be thankful.
I also see lot of tutorials added in DigitalOcean. Is there anything related to text searching algorithm?

I don’t think DigitalOcean is a good place to ask questions about algorithm. You could have tried your luck in StackOverFlow. There are many resources on KMP algorithm (written + video). KMP is pretty advanced topic on pattern searching. So you need to try these resources one by one & see which one clicks for you. If you are struggling about KMP concept, you can check https://www.w3spot.com/2020/07/kmp-algorithm-explained-in-plain-english.html . This article has some good examples. You can follow them. You should be able to understand the concept & time complexity of the algorithm.
