[old] Median

[old] Median


중앙값(Median)은 정렬된 배열에 대하여 배열을 절반으로 나누는 값을 말합니다. 요소의 총 갯수가 홀수인 배열의 중앙값은 배열의 정 가운데 위치한 값이 되고, 짝수 갯수의 요소를 가진 배열의 중앙값은 가운데에 위치한 두 요소의 평균값으로 나타냅니다. 이 미션의 목표는 비어있지 않은 자연수의 배열 X로부터 중앙값을 찾아내는 것입니다.

입력: 배열(정수의 리스트)

출력: 중앙값(정수 또는 부동소수점)


median([1, 2, 3, 4, 5]) == 3
median([3, 1, 2, 5, 3]) == 3
median([1, 300, 2, 200, 1]) == 2
median([3, 6, 20, 99, 10, 15]) == 12.5
