data-structures

问题 I need a data structure that can sort objects by the float keys they're associated with, lowest first. The trouble is that the keys represent cost so there are often duplicates, I don't care about this because if two have the same cost I'll just grab the first as it makes no difference, the problem is that the compiler complains. Is there a data structure that behaves in the same way but allows duplicate keys? EDIT - I still need the duplicates though because if one turns out to be a dead-end

问题 I am in the process of converting my Tournament Organizer software, which allows the creation and manipulation of Double Elimination Tournaments, to use the MVVM design pattern so that it can be more easily tested. In doing so, I'm separating out the 'model' from some code in the UI that directly manipulates the bracket structure. This will be the third iteration of software I've written to handle tournaments. The first was written in PHP and stored the data in a database. The second version

问题 I am trying to fetch the Disaster Recovery Backup details of azure recovery vault services like VM's details, disk details etc. using azure recovery services/ azure recovery backup services client(python). There are no proper examples anywhere in the azure documentation in order to use the client effectively. There are some ways in power shell but I am not eager to learn it. I have already tried this but it has no proper examples. I also am able to create RecoveryServicesClient from azure

问题 I'm currently learning about trees using java and i have some errors going on here in the insertion of items in a binary tree I don't why it doesn't work this is the code: tree node: public class TNode { int data; TNode left; TNode right; public TNode(int data) { this.data = data; left = null; right = null; } } tree class: public class Tree { TNode root; public Tree(){ root = null; } public TNode insertNode(TNode item, int d) { if (item == null) { return new TNode(d); } if (d < item.data) {

问题 I want to augment an avl tree to add extra properties to each node such as number of nodes it contains (i.e. in its subtree). From this avl java implementation code here http://www.blackbam.at/blackbams-blog/2012/05/04/avl-tree-implementation-in-java/ I want to add certain code to it, so that each node will contain a size element. In the AvlNode class, I changed it to: /** Here is the AVL-Node class for Completenesse **/ public class AvlNode { public AvlNode left; public AvlNode right; public

问题 This question already has answers here : How to remove duplicated items in a sorted vector (7 answers) Closed yesterday . I've been trying to solve an "easy" leetcode question for two hours now where I need to remove every instance of an int that appears more than once then add the non dupes together. I've tried about 10 different ways and I can only get it to go down to one copy of each int. Here is the nicest solution I've written, but given input {1,2,2,3,4} it would return {1,2,3,4}
