osaStringDistance function
Levenshtein distance is a string metric for measuring the difference between two sequences. Informally, the Levenshtein distance between two words is the minimum number of single-character edits (insertions, deletions or substitutions) required to change one word into the other
Implementation
int osaStringDistance(String a, String b) {
return osaDistance(a.codeUnits, b.codeUnits);
}
