Polynomial Hashing: The Rolling Hash Function Based on Polynomials
Polynomial hashing is a versatile technique widely used in computer science, especially in string algorithms, to compute the hash value of a sequence of characters. One of the most notable features of polynomial hashing is the ‘rolling’ nature, which allows for the efficient recalculation of hash values as a window slides over a...
Rabin-Karp Algorithm: A Deep Dive into Substring Search
Searching for a substring within a larger text is a common task in computer science. While there are numerous algorithms for this purpose, the Rabin-Karp Algorithm stands out because of its elegance and efficiency in certain scenarios. Based on a hashing technique, it can help locate a pattern inside a text in linear time. How...
