问题 I've got arm that creates notification hub instance I imported certificate with password into key vault, and now I want to use that certificate as apns of notification hub for apple. I am trying something like this but always get bad request: "type": "Microsoft.NotificationHubs/namespaces/notificationHubs", "apiVersion": "2017-04-01", "name": "[concat(parameters('namespaces_nhn_ecosystem_name'), '/nh-ecosystem-', parameters('environmentSuffix'))]", "location": "[resourceGroup().location]",

问题 Hello Stackoverflow people, I have a nested dictionary with lists as values and I want to create a dict where all the list entries get their corresponding key as value. Example time! # what I have dict1 = {"A":[1,2,3], "B":[4,5,6], "C":[7,8,9]} # what I want dict2 = {1:"A", 2:"A", 3:"A", 4:"B", 5:"B", 6:"B", 7:"C", 8:"C", 9:"C"} Any help will be much appreciated! 回答1: Try this dict1 = {"A":[1,2,3], "B":[4,5,6], "C":[7,8,9]} dict2= {} for keys,values in dict1.items(): for i in values: dict2[i]

问题 The report data we receive from analysts come in Table format with arbitrary structure. All we know is that each row has a CustomerId column. But the others, we do not know and can vary every time. The destination system that receives this data only does in Key/Value format so we have to convert the report tables into Key/Value. So, if for instance, the source report table has the following structure: CREATE TABLE [dbo].[SampleSourceTable]( [CustomerId] [bigint] NULL, [Column1] [nchar](10)

I'm developing a Java application which is dealing with a huge amount (~ 1.000.000) of key-value-pairs. The keys have a fixed size

问题 I have a databases that I will be pulling the array of objects below. I want to create a tree structure from it. When the parent_id is nil then its a top level Category. If the parent_id is not nil then it a subcategory of the id value of parent_id. The best solution I have come up with was to loop through the set to get the top level categories then continue looping through until I have organized. Ultimately the table will be less than 500 records but there is no guarantee of that. So

问题 I have an object that looks like this: var obj = { thingA: 5, thingB: 10, thingC: 15 } I would like to be able to select the key/value pair thingA: 5 based on the fact that 5 is the smallest value compared to the other key/value pairs. 回答1: Nothing built-in does that, but: var minPair = Object.keys(obj).map(function(k) { return [k, obj[k]]; }).reduce(function(a, b) { return b[1] < a[1] ? b : a; }); minPair // ['thingA', 5] Or, sans ECMAScript 5 extensions: var minKey, minValue; for(var x in

问题 Having a sorted dict (hash table, map or whatever key/value structure) you can easily have a binary search to look for an item. If we assume the keys are unique but values could be repeated, what data structure can we use to have O(log n) retrieval for keys and also O(log n) query to find count of values=something in the given data? 回答1: Two binary search trees, one for keys, second for values, with mutual pointers will provide the required functionality. The pointers can be many-to-one from

问题 I have a dictionary called spectradict which is composed of 5 different keys (multiple values per key), and I'd like to multiply each value under 4 of the keys by some constant A. I've figured out how to multiply all the values (under all the keys) by the constant: spectradict.update((x, y*A) for x, y in spectradict.items()) But I only want the values under spectradict['0.001'] , spectradict['0.004'] , spectradict['0.01'] , spectradict['0.02'] to be multiplied by A. I want the spectradict['E'

问题 I have a JSON file A.json which contains multiple dictionaries. And I want to remove common key-value pairs from key "model" grouped by brand . For example, consider the brand: "Ford": {"Number": '123', "brand": "Ford", "model":{"Mustang1":"2.64", "Mustang2":"3.00", "Mustang3":"1.00", "Mustang4":"1.64"}} {"Number": '891', "brand": "Ford", "model":{"Mustang1":"2.64", "Mustang8":"3.00", "Mustang3":"1.00", "Mustang6":"1.64"}} Keys in key model which are common across both the dictionaries are

问题 Is this the best way to get the key and value from a JS object: function jkey(p){for(var k in p){return k;}} function jval(p){for(var k in p){return p[k];}} var myobj = {'Name':'Jack'}; alert(jkey(myobj)+' equals '+jval(myobj)); Or is there a more direct or faster way ?? What I need to do is to me able to call the key-name and value seperately. the functions work and return the keyname and value, I just wondered if there was a smaller, faster, better way. Here's a better example, I want to
