So the number of elements on the left side of the array will be equal or less than the number of elements on the right side. Now, let us consider the case of an array with odd number of elements. Array = [9,11,16,7,2] Sorted array = [2,7,9,11,16]

WebThe median of a list of numbers is essentially its middle element after sorting. The same number of elements occur after it as before. Given a list of numbers with an odd number of elements, find the median? Example. The sorted array . The middle element and the median is . Function Description. Complete the findMedian function in the editor below. WebThe median is the middle value in an ordered integer list. If the size of the list is even, there is no middle value. So the median is the mean of the two middle values. For examples, if arr = [2, 3 ,4], the median is 3. For examples, if arr = [1, 2,3 ,4], the median is (2 + 3) / 2 = 2.5. You are given an integer array nums and an integer k.
WebFeb 28, 2024 · Time Complexity: O(N*(K+n)) Here N is the length of dictionary and n is the length of given string ‘str’ and K – maximum length of words in the dictionary. Auxiliary Space: O(1) An efficient solution is we Sort the dictionary word.We traverse all dictionary words and for every word, we check if it is subsequence of given string and at last we … WebUse the numpy.median () function without any arguments to get the median of all the values inside the array. For multi-dimensional arrays, use the axis parameter to specify the axis along which to compute the median. For example, for a 2-D array – Pass axis=1 to get the median of each row. Pass axis=0 to get the median of each column.
WebOct 21, 2024 · Hence, the median is 3 Input: A [] = {1, 2, 3, 4}, B [] = {5, 6} Output: 3.5 Explanation: Union of both arrays: {1, 2, 3, 4, 5, 6} Median = (3 + 4) / 2 = 3.5 Simple approach: Using Extra Space The most basic approach is to merge both the sorted arrays using an auxiliary array.

WebFind median of unsorted array in O ( n) time. To find the median of an unsorted array, we can make a min-heap in O ( n log n) time for n elements, and then we can extract one by one n / 2 elements to get the median. But this approach would take O ( n log n) time.
