引言一个数据集合的中值(Median)通常是很一个很有价值的统计指标,由于它对异常数据不敏感,所以一般会比平均值(Mean)更能体现数据集合数据的“平均水平”。然而,对于无序数据序列求中值在实现上却没有求平均值那样简单优美的O (N)复杂度的算法。最容易想到的做法是先对数据进行排序,然后取中点的值,...

【题意】给出一串数字,问中位数大于等于X的连续子串有几个。(这里如果有偶数个数,定义为偏大的那一个而非中间取平均)【思路】下面的数据规模也小于原题,所以要改成__int64才行。没找到测试数据,自己编的几组。简单来说读入每个数,大于等于中位数设为1,小于设为-1,前i个数的和建立一个树状数组,求逆序...
