力扣leetcode.cn/problems/closest-binary-search-tree-value-ii/ 之前270题的强化版,本题要求找出最近target的k个值。最直观的想法就是先执行一次中序遍历,然后利用排序或者快速选择找出最接近target的top k个值,不过在这里还存在更好的做法。 直接套用270题的做法,从根节点向下寻找最接近target的节点值,并将...

272 Closest Binary Search Tree Value II // #272 二叉搜索树中最近的值2 描述: 和之前一样,不过这次要找的是最接近的k个值。 // #272 Description: Closest Binary Search Tree Value II | LeetCode OJ 解法1:最接近的k个值,一定分布在target的左和右。于是我们用二分搜索找到分界线,然后往两边遍历即可...
