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

Just use cin instead of getline.I have solved many problem where getline doesn't work but cin does.Mayber they have used space to separate int the test case. |

cin.get() gives WA while scanf gives AC. What is the reason? |

nothing to worry just declare 2001x2001 global matrix if you are going to use this approach

Even though the input descriptions says that there are 10 test cases. Reading the number of test cases is mandatory. Else, WA !! |

All input lines could have "\r\n" sequence at the end, not just '\n' character, be careful with hand-written input and with library-implemented readliners. |
