You need to output the length of D. Input The first line of the input contains an integer T(T = 20) which means the number of test cases. For each test case, the first line only contains string A, the second line only contains string B, and the third only contains string C. The length of each string will not exceed 1000, and string C should always be the subsequence of string A and string B. All the letters in each string are in lowercase. Output For each test case, output Case #a: b. Here a means the number of case, and b means the length of D. Sample Input
Sample Output
Hint For test one, D is "aaaa", and for test two, D is "acf". Source
