Welcome to this insightful lesson. Today's focus will be on string searching algorithms, a fundamental part of programming often encountered in software development, the design of databases, and information retrieval. This lesson will walk you through the intricacies of these algorithms, explaining the principles behind each one.

For instance, consider the KMP string searching algorithm, where the essence of its design is to eliminate the need to backtrack by retaining the information elicited from previous comparisons. If, at some point in the pattern, there's a mismatch, the algorithm does not begin matching the pattern with the text from the start but from a pre-computed point that takes into account all previous comparisons. It's an efficient way to avoid redoing work!

There are many details regarding this algorithm, but here is what its implementation might look like in C#:

Feel free to ask questions to clarify the details!
