Common sub-sequence
Time Limit: 1000ms
Memory Limit: 65536kb Description
A new sequence after removing 0 or more characters sequentially from original sequence is called sub-sequence of original sequence.For example: "0123" is the sub-sequence of "2011123", while it is not the sub-sequence of "2111023". Given three sequences composed of characters '0' to '9', can you count the number of non-empty common sub-sequence of them? Notice: same sub-sequence should be counted only once. Input
The input consists of multiple test cases. The first line, an integer T (1<=T<=100), indicates the number of cases. Each test case has only one line, containing three sequences whose length is at most 40. Output
Output the answer of each case.
