String Search Algorithm in java OR String Matching Algorithm in java: KMP Algorithm is one of the many string search algorithms which is better suited in scenarios where ‘pattern to be searched’ remains same whereas ‘text to be searched’ changes.
Knuth-Morris-Pratt Algorithm (KMP) detailed analysis
Understanding this would show us what a careful algorithmic thinker would code even for a small problem like this. This is one of the algorithms which is easy to implement but one needs lot of attention and hard work to understand the algorithm.
Problem Statement: lets assume we want to search for the pattern P in the text T.
T: [abcabdabcabdabcabdabdabc]
P: [abcabdabc]
This algorithm is executed in two phases.
- Preprocessing Phase
- Search Phase
