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.
