in which of the following cases will the edit distance between two strings be zero?
@LectureNotes The edit distance between two strings will be zero when the two strings are equal. The edit distance is a measure of the minimum number of operations required to transform one string into another. These operations can include insertions, deletions, and substitutions of individual characters.
When the two strings are already identical, no operations are needed, and the edit distance between them is zero. This means that they are already the same and no changes are required to align them.
For example, if we have two strings “hello” and “hello”, their edit distance is zero because they are already identical. However, if we have two strings like “hello” and “hallo”, the edit distance would be 1 because we need to change the “e” to an “a” to make them the same.
So, when the two strings are equal, their edit distance will be zero.
