Can you solve this real interview question? Find the Kth Smallest Sum of a Matrix With Sorted Rows - You are given an m x n matrix mat that has its rows sorted in non-decreasing order and an integer k. You are allowed to choose exactly one element from
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. BFS + Priority Queue Time Complexity O(klogk) Space Complexity 每一轮最多出一个node,放两个Node, 进行了k轮 ...
题目: 二叉搜索树中第K小的元素:给定一个二叉搜索树,编写一个函数 kthSmallest 来查找其中第 k 个最小的元素。 说明: 你可以假设 k 总是有效的,1 ≤ k ≤ 二叉搜索树元素个数。 思路: 二叉搜索树具有良好的性质,一个节点左边的数小于该节点,右边的数大于该节点,因
