EDIST - Edit distance
You are given two strings, A and B. Answer, what is the smallest number of operations you need to
transform A to B?
Operations are:
- Delete one letter from one of strings
- Insert one letter into one of strings
- Replace one of letters from one of strings with another letter
Input
T - number of test cases
For each test case:
- String A
- String B
Both strings will contain only uppercase characters and they won't be longer than 2000 characters.
There will be 10 test cases in data set.
Output
For each test case, one line, minimum number of operations.
Example
Input: 1 FOOD MONEY Output: 4

@abbi_18 At any given point you just require only n-elements, hence you don't need to store n*n elements. If you think in this direction you'll be able to reduce space complexity from O(n^2) to O(n). |
