Introduction to Pattern Searching Algorithms

Pattern Searching algorithms are used to find a pattern or substring from another bigger string. There are different algorithms. The main goal to design these type of algorithms to reduce the time complexity. The traditional approach may take lots of time to complete the pattern searching task for a longer text.

Here we will see different algorithms to get a better performance of pattern matching.
