According to your reasoning the optimal minimum difference is (7 - 3) - (1 + 3) = 0. But what do you do with the tower of height 4? You either need to increase or decrease this, so the minimum difference you can achieve is in fact 3 in this example.

Nettet12. nov. 2024 · Among all possible rooted trees, those with minimum height. ... 2024-11-12. Algorithm. LeetCode/Minimum Height Tree Problem Summary. For an undirected graph with tree characteristics, we can choose any node as the root. The result graph is then a rooted tree. Nettet25. mar. 2024 · In below diagram all node are made as root one by one, we can see that when 3 and 4 are root, height of tree is minimum (2) so {3, 4} is our answer. Recommended: Please try your approach on {IDE} …
NettetExplanation: we get the minimum height as 2 when node 3 and 4 are selected as roots & hence the answer is [3,4] Approach The most obvious intuition that comes to mind is to apply the shortest path algorithm to find the distance between the root node to all other nodes. This approach requires applying Dijkstra from all nodes. NettetIf you are able to come up with a solution which works correctly, just isn't the best one, that's still a success, coming up with a brute force solution is a bare minimum in an interview. You can try improving the brute force solution by using some optimizations, that might not lead you to the optimal solution, but improving a solution is a great skill.
NettetWe have to either increase or decrease height of every tower by k (only once) where k > 0. The task is to minimize the difference between the heights of the longest and the shortest tower after modifications, and output this difference. Examples: Input : arr [] = … Nettet面试题 04.02. 最小高度树 - 给定一个有序整数数组,元素各不相同且按升序排列,编写一个算法,创建一棵高度最小的二叉搜索树。 示例: 给定有序数组: [-10,-3,0,5,9], 一个可能的答案是:[0,-3,9,-10,null,5],它可以表示下面这个高度平衡二叉搜索树: 0 / \ -3 9 / / -10 5
NettetReturn the number of indices where heights[i] != expected[i]. Example 1: Input: heights = [1,1,4,2,1,3] Output: 3 Explanation: heights: [1,1,4,2,1,3] expected: [1,1,1,2,3,4] Indices 2, 4, and 5 do not match. Example 2: Input: heights = [5,1,2,3,4] Output: 5 Explanation: …
