public build(p: ArrayLike, pi: number, pj: number, t: number[], ti: number) source

import build from '@string-data-structure/failure-function/src/build.js'

Computes the failure function for input string.

This is the "next[j]" table found in "Fast pattern matching in strings" by Knuth, Morris, and Pratt, although here indices are 0-based hence all indices and inputs are one less than in that paper.

NOTE The main loop is somewhat unrolled for faster execution. This was not benchmarked.

Params:

Name	Type	Attribute	Description
p	ArrayLike
pi	number
pj	number
t	number[]
ti	number
