特定字符串的 Damerau–Levenshtein 距离不对称性

Describe the bug When using the DamerauLevenshteinDistance function on certain strings, the returned distance sometimes depends on the order in which the two strings are passed as arguments. From what I understand, the Damerau–Levenshtein distance should be symmetric (i.e., distance(a, b) should equal distance(b, a)). However, for at least one pair of strings, calling the function with reversed arguments yields a different result, which indicates unexpected, asymmetric behavior.
