문제
번역본 보기Whole 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.
제약 조건
−1,000,000 ≤ number ≤ 1,000,000. The input is finite and has at most two decimal places.
예시
예시 1
입력:
number = 14
예상 출력:
expected = "even"입력:
double number = 14;
예상 출력:
std::string expected = "even";입력:
double number = 14;
예상 출력:
string expected = "even";설명
14 = 2 × 7, so it is divisible by 2.
예시 2
입력:
number = 3.5
예상 출력:
expected = "neither"입력:
double number = 3.5;
예상 출력:
std::string expected = "neither";입력:
double number = 3.5;
예상 출력:
string expected = "neither";설명
3.5 has a fractional part, so it is neither an odd nor an even integer.
