Problema
Ver traducciónWhole 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.
Restricciones
−1,000,000 ≤ number ≤ 1,000,000. The input is finite and has at most two decimal places.
Ejemplos
Entrada:
number = 14
Salida esperada:
expected = "even"
Entrada:
double number = 14;
Salida esperada:
std::string expected = "even";
Entrada:
double number = 14;
Salida esperada:
string expected = "even";
Explicación
14 = 2 × 7, so it is divisible by 2.
Entrada:
number = 3.5
Salida esperada:
expected = "neither"
Entrada:
double number = 3.5;
Salida esperada:
std::string expected = "neither";
Entrada:
double number = 3.5;
Salida esperada:
string expected = "neither";
Explicación
3.5 has a fractional part, so it is neither an odd nor an even integer.
