Diophantine reciprocals IIIn the following equation x, y, and n is positive integers.For n = 4 There is exactly three distinct solutions:It can be verified, that's when n = 1260 There was 113 distinct solutions and this was the least value of n for which the Tota L number of distinct solutions exceeds one hundred.What's the least value of n for which the number of distinct solutions exceeds four million?Note:this problem is a much more difficult version of problem 108 and as it's well beyond the

Given a binary tree, determine if it is height-balanced.For this problem, a height-balanced binary tree was defined as a binary tree in which the depth of the subtrees of the Y node never differ by more than 1.Determine whether a tree belongs to a balanced binary treeJudge the left and right node depth of the main node, if not in " -1,1", return false, otherwise, continue to determine whether its left and right node is a balanced binary tree;Returns false as long as there is no satisfaction.Code

Leetcode [110]-Balanced Binary Tree, leetcode-balanced Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. Determine whether a tree belongs to a balanced binary tree Determine the depth difference between the left and right nodes of the master node. If it is not in [-], false is returned. O

previous information before reaching the current node. We should is able to mainpulate on the information, and pass it to next recursion level. The big problem comes out:if we manipulate on the same object (list), this could is a disaster. Since Each recursion level has a sparate searching branches.The solution:we make a copy of passed in list, thus we can use the information recorded in the list, without affecting OT Her searching branches.

Question: In the 110-meter column, athletes can run in three states: 1. The State consumes physical strength and runs fast. 2. The State does not consume physical strength. 3. The State recovers physical strength and runs slowly. The maximum physical strength is m, and the initial physical strength is full. Now I want to know the minimum time to complete the whole process. Analysis: DP, full backpack. The question is a backpack with a negative volume.
