문제

A start-up company wants to hire you to write a painting program. As part of your interview, they have asked you to write a program that can draw filled and empty rectangles of different colors on a square grid of pixels. An empty rectangle will have a border that is one pixel thick. If a new rectangle is requested, it should completely overwrite what, if anything, was in that area.

입력

The first line of input is the number of test cases that follow. Each test case starts with an integer N (1 ≤ N ≤ 100) on a line by itself which is the width and height of the pixel grid; all pixel grids are square. The next line contains an integer M (0 ≤ M ≤ 100) which represents the number of rectangles to draw. The next M lines start with either the string “Filled” or “Empty” stating whether to draw a filled or an empty rectangle. This is followed by 4 space-separated integers: X Y W H where X and Y are the position of the bottom-left corner of the rectangle, W is the width of the rectangle, and H is the height. This is then followed by a space and then a single character C, representing the color to draw the rectangle. C will be an uppercase letter between A and Z. X is the horizontal axis, meaning the number of characters from the left. Y is the vertical axis, meaning the number of characters from the bottom. All rectangles will be completely contained by the pixel grid. Note that the bottom-left corner of the grid is represented by the point (1,1).

출력

For each case output “Case x:” where x is the case number, on a single line by itself. Then output N lines of N characters each representing the final drawing of the paint program. If nothing was drawn at a particular pixel, a ‘.’ should be outputted instead.
