Function std.algorithm.comparison.levenshteinDistanceAndPath
Returns the Levenshtein distance and the edit path between s and
t.
Tuple!(size_t,EditOp[]) levenshteinDistanceAndPath(alias equals, Range1, Range2)
(
Range1 s,
Range2 t
)
if (isForwardRange!Range1 && isForwardRange!Range2);
Tuple!(size_t,EditOp[]) levenshteinDistanceAndPath(alias equals, Range1, Range2)
(
auto ref Range1 s,
auto ref Range2 t
)
if (isConvertibleToString!Range1 || isConvertibleToString!Range2);
Parameters
| Name | Description |
|---|---|
| equals | The binary predicate to compare the elements of the two ranges. |
| s | The original range. |
| t | The transformation target |
Returns
Tuple with the first element being the minimal amount of edits to transform s into t and the second element being the sequence of edits to effect this transformation.
Allocates GC memory for the returned EditOp[] array.
Example
string a = "Saturday", b = "Sundays";
auto p = levenshteinDistanceAndPath(a, b);
writeln(p[0]); // 4
assert(equal(p[1], "nrrnsnnni"));
