What is the edit distance between the strings "abcd" and "ac - Practice - ObjectiveMcq

What is the edit distance between the strings "abcd" and "acbd" when the allowed operations are insertion, deletion and substitution?

Correct Answer: B — 2

The string "abcd" can be changed to "acbd" by substituting "b" with "c" and "c" with "b". Thus, the edit distance is 2.
