WebWhich of the algorithm is used for string matching? There are many algorithms for string Matching, like Naive string matching, Rabin Karp, KMP string matching algorithm, Knutt Morris Pratt, Boyer-Moore, etc. Out of these, the most intuitive approach is the Naive String matching algorithm. What is the complexity of the naive string matching ... WebLimitations of the Rabin-Karp Algorithm. Spurious Hit increases the worst-case complexity of the algorithms. When the hash value matches the hash value of the pattern, but the string is different from the pattern, then it's called a Spurious Hit. In order to reduce Spurious Hit, we use modulus.That reduces the chances of Spurious Hit to a great extent.
