25088번 - Punched Cards 서브태스크다국어

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 $R×C$ matrix without the top-left cell. That means, it has $(R⋅C)-1$ 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 $R=3$ rows and $C=4$ columns:

..+-+-+-+
..|.|.|.|
+-+-+-+-+
|.|.|.|.|
+-+-+-+-+
|.|.|.|.|
+-+-+-+-+

There are more examples with other sizes in the samples below. Given the integers $R$ and $C$ describing the size of a punched card, print the ASCII art drawing of it as described above.

The first line of the input gives the number of test cases, $T$. $T$ lines follow, each describing a different test case with two integers $R$ and $C$: the number of rows and columns of the punched card that must be drawn.

For each test case, output one line containing Case #x:, where $x$ is the test case number (starting from 1). Then, output $(2⋅R)+1$ additional lines with the ASCII art drawing of a punched card with $R$ rows and $C$ columns.

• $1≤T≤81$.
• $2≤R≤10$.
• $2≤C≤10$.

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 $R⋅C+3$ periods.
