Given a n x n matrix where each of the rows and columns are sorted in ascending order, find the kth smallest element in the matrix. Note that it is the kth smallest element in the sorted order, not the kth distinct element. Example: matrix = [ [ 1, 5, 9], [10, 11, 13], [1...
Given ann x nmatrixwhere each of the rows and columns is sorted in ascending order, returnthekthsmallest element inthe matrix. Note that it is thekthsmallest elementin the sorted order, not thekthdistinctelement. You must find a solution with complexity better thanO(n2). Example 1: Input: ...
这里我们做类似的事情,每当matrix[row][0]小于堆顶元素时,我们就将整个一行都推到heap里面。还是要注意heap里需要预存一个MaxInt,否则可能出现pop空堆的情况。 1classSolution(object):2defkthSmallest(self, matrix, k):3"""4:type matrix: List[List[int]]5:type k: int6:rtype: int7"""8ans =[]...
