Article Introduction：How to use PHP and GMP to implement the Miller-Rabin primality test of large numbers Introduction: Prime numbers play an important role in cryptography and computer science. The Miller-Rabin primality test is a probabilistic algorithm used to test whether a number is prime. It gives the correct answer with a high probability. This article will introduce how to use PHP language and GMP library (GNUMultiplePrecisionArithmeticLibrary) to implement Miller-

Article Introduction：What is the Rabin-Karp algorithm? The Rabin-Karp algorithm is a string pattern matching algorithm that efficiently searches for occurrences of patterns in larger texts. It was developed in 1987 by Michael O. Rabin and Richard M. Karp. This algorithm utilizes hashing techniques to compare patterns and hash values ​​of text substrings. Here's how it works: Calculate the hash of the first window of pattern and text. Slide the pattern over the text, one position at a time and compare the hashes. If the hashes match, the characters of the pattern and the current window of text are compared to confirm the match. If there is a match, record the position/index of the match. Computes the hash of the next window of text using a rolling hash function. Repeat steps 3 to 5
