# Rabin Karp Algorithm
In computer science, the Rabin–Karp algorithm or Karp–Rabin algorithm
is a string searching algorithm created by Richard M. Karp and
Michael O. Rabin (1987) that uses hashing to find any one of a set
of pattern strings in a text.
## Complexity
For text of length `n` and `p` patterns
of combined length `m`, its average and best case running time is
`O(n + m)` in space `O(p)`, but its worst-case time is `O(n * m)`.
## Application
A practical application of the algorithm is detecting plagiarism.
Given source material, the algorithm can rapidly search through a paper
for instances of sentences from the source material, ignoring details
such as case and punctuation. Because of the abundance of the sought
strings, single-string searching algorithms are impractical.
