LeetCode Median of Two Sorted Arrays
Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). Example 1: nums1 = [1, 3] nums2 = [2] The median is 2.0 Example 2: nums1 = [1, 2] nums2 = [3, 4] The median is (2 + 3)/2 = 2.5 解决方法1：最直接的想法，将两个数组合并后排序，再取中位数 class Solution: def findMedianSortedArrays

Sliding Window Median
题目要求 Median is the middle value in an ordered integer list. So the median is the mean of the two middle value. Examples: [2,3,4] , the median is 3 [2,3], the median is (2 + 3) / 2 = 2.5 Given an array nums, there Your job is to output the median array for each window in the original array. Window position Median --------------- ----- [1 3 -1] -3 5 3 6 7

Python计算中位数 numpy.median
numpy模块下的median作用为： 计算沿指定轴的中位数 返回数组元素的中位数 其函数接口为： median(a, axis=None, out=None, (a) # 1，2，3，4，7，10 # (3+4)/2 = 3.5 3.5 >>> np.median(a, axis=0) #(10+3)/2 = 6.5 #(7+2)/2 = 4.5 #(4+1 )/2 = 2.5 array([ 6.5, 4.5, 2.5]) >>> np.median(a, axis=1) #奇数个数中位数 array([ 7., 2.]) >>> m = np.median (a, axis=0) >>> out = np.zeros_like(m) >>> np.median(a, axis=0, out=m) array([ 6.5, 4.5, 2.5]) >>> m array([ 6.5, 4.5, 2.5]) >>> b = a.copy() >>> np.median(b, axis=1, overwrite_input=True) array([ 7

Excel公式技巧74：巧用MEDIAN函数
然而，我们有一种更好的方式，就是使用MEDIAN函数。上面的判断条件也可以使用公式： =IF(MEDIAN(A1,C1,A2)=C1,"是","否") 结果一样，如下图2所示。 ? 图2 同样，可以将MEDIAN函数用于日期的判断中，如下图3所示。 ? 图3 使用公式： =IF(MEDIAN(A1,C1,A2)=C1,"是","否") 来判断指定的日期是否位于两个日期之间。 注：MEDIAN函数返回一组数的中值。利用其计算特点，对于含有3个参数的MEDIAN函数来说，若这3个参数按从小到大排列，则其中间的一个数恰好是中间。
