在一个由n个元素组成的集合中,第i个顺序统计量(order statistic)是该集合中第i小的元素。用非形式化的描述来说,一个中位数(median)使它所属集合的“中点元素”。当n为奇数时,中位数是唯一的,位于i=(n+1)/2处。当n为偶数时,存在两个中位数,分别位于i=n/2和i=n/2+1...

In one well-known algorithm of finding the k-th order statistics we should divide all elements into groups of five consecutive elements and find the median
of each five. A median is called the middl...

题目描述:
Given an increasing sequence S of N integers, the median is the number at the middle position. For example, the median of S1={11, 12, 13, 14} is 12, and the median of S2={9, 10, 15, 16, 17} is 15. The median of two sequences is defined to be...
