sorting

问题 I try to get some data from tab A to tab B using the query function. This all works fine untill I include some data of tab B into the object in the query function. The thing is, I want to create a scoring sheet that calculates the constructor points based of the first sheet with the driver standings. So tab A looks something like this: Peter Wright - Team Fast Racers - 85 Cameron Bright - Team Quickies - 60 Marc Feiner - Team Fast Racers - 20 In this example the number correspond to a total

问题 I am trying to pass some ids into an in-clause on a sorted index with the same order by condition but the query planner is explicitly sorting the data after performing index search. below are my queries. Generate a temporary table. SELECT a.n/20 as n, md5(a.n::TEXT) as b INTO temp_table From generate_series(1, 100000) as a(n); create an index CREATE INDEX idx_temp_table ON temp_table(n ASC, b ASC); In below query, planner uses index ordering and doesn't explicitly sorts the data.(expected)

问题 This is a follow-up question of exact string search in an array of strings. There is another thing if the document has a publishing date. { "datePublished":"2020-05-22T15:06:00.000Z", "locations":[ "Landkreis Cloppenburg", "Berlin" ] } and sort them with the latest publication date. Then the result is coming back with the Landkreis Cloppenburg if I have this in the query: "sort": [ { "doc.datePublished":{ "order":"desc" } } ] 回答1: the correct query should be like below { "sort": [ {

问题 I have a problem when sorting a generic list in C# I have a List<MyObjects> myList , and MyObject has a string property. Now it looks like this when sorting descending 2.4.88 2.4.70 2.4.164 -> this is wrong 2.4.15 How do I sort my list? I have tried: myList.sort(delegate(MyObjects obj1, MyObjects obj2) { return obj2.version.CompareTo(obj1.version); }); Its not an option to use Linq (older framework) UPDATE: My list can also contains N/A 回答1: You cannot compare as strings, because obviously

问题 Is there a way to turn a Binary to a sorted array without having to traverse the tree for every array index? Node root; Node runner; int current_smallest; void findsmallest(Node root){ //Pre-order traversal if(root == null){ return; }else{ runner = root; if(current_smallest == null){ current_smallest = runner.element; }else{ if(current_smallest > runner.element){ current_smallest = runner.element; } } findsmallest(runner.left); findsmallest(runner.right); } } void fill_array( int [] array ){

问题 Hi I have a lookup type that stores strings and ints. static Lookup<string, int> lookup; lookup = (Lookup<string, int>)list.ToLookup(i => i.IP, i => i.Number); But now I need to sort this lookup by the values (number), and get the top 10 keys with their values. How is this possible? 回答1: I'm not sure why you are casting a Lookup<string, int> to a Lookup<string, string> , but the general answer you want is: var list = new List<Test> { new Test { IP = "A", Number = 1 }, new Test { IP = "A",

问题 I am making an OCR, I am using contours detection, I have extracted words and drawn bounding boxes but the problem is that when I crop the individual word, they are not in sorted order. I have tried sorting methods mentioned in this link to sort the contours but they work best on objects but in my case i want to make the order exact. sometimes the sorting is not the best solution it changes pattern of words as different words have different size of bounding boxes in same line and values of 'x
