Odd, Even, or Neither

Whole numbers divisible by 2 are even; other whole numbers are odd. A number with a fractional part is neither. Zero is even, and negative integers follow the same rule.

Implement number_parity(number).

Input

number: The number to classify.

Output

Return odd, even, or neither as lowercase text.

Vincoli
