Statement
Goal
Designers are placing shapes of different sizes and colors on the canvas of an image editor.About Colors
The shapes have primary colors defined in RGB color notations. Red is (255, 0, 0); Green is (0, 255, 0); Blue is (0, 0, 255). Besides these, they also use Yellow (255, 255, 0), Cyan (0, 255, 255) and Magenta (255, 0, 255).
All shapes have a very thin black border (0, 0, 0) and are on a white background (255, 255, 255).
The shapes are defined as transparent so that when one shape is overlaying another, their colors will mix to reveal a new color. When two or more colors blend together, the new color is the average of all layer's colors.
For example, when R and G blend, the mixed color is (128, 128, 0). When Y, M and G mix, the result will be ((255+255+0)/3, (255+0+255)/3, (0+255+0)/3), which is (170, 170, 85). We round the decimal results to get the nearest integers (i.e. 10.4 is regarded as 10; 10.5 is regarded as 11).
Black and White do not have blending effects.
In the final design, only squares and circles are used. Designers want to have a program to automatically calculate the color at any chosen point.
When a chosen point is within one or more shapes, report the color or mixed color at that point.
When a chosen point is outside the shapes, report White (255, 255, 255).
When a chosen point is on the borderline of any shape, report Black (0, 0, 0).
Input
Line 1: Integer S and P, for the number of Shapes and number of checking points.
Next S lines: Each line defines one Shape by seven elements, space separated:
name is either SQUARE or CIRCLE
x0 y0 are integers. For a circle, this is the coordinates of the center. For a square, it is the coordinates of the lower-left corner. We are using the Cartesian coordinates system. All square sides are parallel to the x or y axis.
len is an integer. For a circle, it is the radius. For a square, it is the side length.
R G B are integers, color values of this shape.
Next P lines: Each line defines a point by integers x y. You have to calculate the color at each of the points.

Write P lines Each line is a RGB color notation in format (R, G, B).
Constraints
1 ≤ S ≤ 50
1 ≤ P ≤ 50
0 ≤ x, y ≤ 1000 (This is the canvas size limit)
1 ≤ len ≤ 500
0 ≤ R, G, B ≤ 255
Some shapes may be partially drawn outside the canvas. Your business is within the canvas only.
