Roulette Wheel Colors

On a roulette wheel, the pockets are numbered from 0 to 36. The colors of the pockets are as follows:

■ Pocket 0 is green.

■ For pockets 1 through 10, the odd-numbered pockets are red and the even-numbered pockets are black.

■ For pockets 11 through 18, the odd-numbered pockets are black and the even-numbered pockets are red.

■ For pockets 19 through 28, the odd-numbered pockets are red and the even-numbered pockets are black.

■ For pockets 29 through 36, the odd-numbered pockets are black and the even-numbered pockets are red.

Write a program that asks the user to enter a pocket number and displays whether the pocket is green, red, or black. The program should display an error message if the user enters a number that is outside the range of 0 through 36.
