The edit distance between two strings is the minimum number of operations required to transform one string into the other.
The allowed operations are:
- Add one character to the string.
- Remove one character from the string.
- Replace one character in the string.
For example, the edit distance between LOVE and MOVIE is 2, because you can first replace L with M, and then add I.
Your task is to calculate the edit distance between two strings.
The first input line has a string that contains n characters between A–Z.
The second input line has a string that contains m characters between A–Z.
Print one integer: the edit distance between the strings.
- 1 \le n,m \le 5000
