Mondrian, the painter-elf, has designed a square-shaped Christmas card and has subdivided it into 100 square-shaped cells in a 10 x 10 pattern, as shown in Figure 1.
Furthermore, Mondrian has drawn 30 black circles on his card. Around each of these 30 black circles, Mondrian has constructed a painted region; the blue region, the green region, and the yellow region are shown in picture 1.
