# `gno.land/p/moul/x/daily/levenshtein/v0` **Levenshtein edit-distance** — `Distance`, `Matrix`, `Similarity`. The minimum number of single-character insertions, deletions, or substitutions to turn one string into another. Fully rune-aware, pure (deterministic), two-row DP (`O(min(len))` memory). Ported from Go's `agext/levenshtein`. ```go import "gno.land/p/moul/x/daily/levenshtein/v0" d := levenshtein.Distance("kitten", "sitting") // 3 m := levenshtein.Matrix("kitten", "sitting") // full (7 x 8) DP matrix s := levenshtein.Similarity("kitten", "sitting") // 57 (a 0..100 percentage) ``` **Live demo:** [`r/moul/x/daily/levenshteindemo`](https://github.com/moul/gno-contracts/tree/main/r/moul/x/daily/levenshteindemo/v0) · render it at [`/r/moul/x/daily/levenshteindemo/v0`](https://gno.land/r/moul/x/daily/levenshteindemo/v0). --- Part of **[moul/gno-contracts](https://github.com/moul/gno-contracts)** — moul's versioned gno.land contracts.
