Time Limit: 1000 ms
Memory Limit: 65536 KiB
Problem Description
请定义具有red, orange, yellow, green, blue, violet六种颜色的枚举类型color,根据输入的颜色名称,输出以下六种植物花朵的颜色:
Rose(red), Poppies(orange), Sunflower(yellow), Grass(green), Bluebells(blue), Violets(violet)。如果输入的颜色名称不在枚举类型color中,例如输入purple,请输出I don't know about the color purple.
Input
输入数据有多行,每行有一个字符串代表颜色名称,颜色名称最多30个字符,直到文件结束为止。
Output
输出对应颜色的植物名称,例如:Bluebells are blue. 如果输入的颜色名称不在枚举类型color中,例如purple, 请输出I don't know about the color purple.
Sample Input
blue yellow purple
Sample Output
Bluebells are blue. Sunflower are yellow. I don't know about the color purple.
Hint
请用枚举类型实现。
