1025: SYH’s Easy Area Problem

SYH has drawn a picture which only contains the following gird of pattern:

Which is expressed by: ‘.’, ‘\’, ‘/’.

These red lines can form a close pattern. SYH wants you to calculate the area of the close pattern. Assume that the area of a grid is one.

The first line conatins an integer T, means the number of test cases. For each test case, the first line contains two integers n and m, which means the size of the pattern. Then an n×m pattern followed.

For each test case ouput “Case: #x:y” in a single line. x is the test case number (starting from 1), and y is your answer.
