[GCJ 2022 Qualification] Punched Cards
题目描述
A secret team of programmers is plotting to disrupt the programming language landscape and bring punched cards back by introducing a new language called Punched Card Python that lets people code in Python using punched cards! Like good disrupters, they are going to launch a viral campaign to promote their new language before even having the design for a prototype. For the campaign, they want to draw punched cards of different sizes in ASCII art.
The ASCII art of a punched card they want to draw is similar to an matrix without the top-left cell. That means, it has cells in total. Each cell is drawn in ASCII art as a period (.) surrounded by dashes (-) above and below, pipes (|) to the left and right, and plus signs (+) for each corner. Adjacent cells share the common characters in the border. Periods (.) are used to align the cells in the top row.
For example, the following is a punched card with rows and columns:
..+-+-+-+
..|.|.|.|
+-+-+-+-+
|.|.|.|.|
+-+-+-+-+
|.|.|.|.|
+-+-+-+-+
There are more examples with other sizes in the samples below. Given the integers and describing the size of a punched card, print the ASCII art drawing of it as described above.
输入格式
The first line of the input gives the number of test cases, . lines follow, each describing a different test case with two integers and : the number of rows and columns of the punched card that must be drawn.
输出格式
For each test case, output one line containing Case #x:
, where is the test case number (starting from 1). Then, output additional lines with the ASCII art drawing of a punched card with rows and columns.

Sample Explanation
Sample Case #1 is the one described in the problem statement. Sample Cases #2 and #3 are additional examples. Notice that the output for each case contains exactly periods.
