题目描述: 给定一个 n x n 矩阵,其中每行和每列元素均按升序排序,找到矩阵中第k小的元素。请注意,它是排序后的第k小元素,而不是第k个元素。 示例: matrix = [ [ 1, 5, 9], [10, 11, 13], [12, 13, 15]],k = 8, 返回 13。说明 ...
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 t ...
