sorting

问题 I have the following data: and I was wondering how I could sort these in a specific order. The order needs to be: Yellow, Blue, White, Green, Red and then within those colors, it would show the smallest number first. So in this case, the correct sorting should be: y2, y3, b0, b2, b6, w2, g7, r4 Does anyone have any ideas on how to accomplish that? I'm using underscore.js if that makes it easier. 回答1: This naively assumes that all elements have a valid color (or at least it sorts elements with

问题 this is my code Sub SortMultipleColumns(myline As String) With Worksheets("Result-Inactive").Sort .SortFields.Add Key:=Range("A1"), Order:=xlAscending .SortFields.Add Key:=Range("D1"), Order:=xlAscending .SortFields.Add Key:=Range("J1"), Order:=xlAscending .SetRange Range("A1:C" & myline) .Header = xlYes .Apply End With End Sub I get the following error and I dont undertsand why "Run time error '1004' the sort reference is not valid. MAke sure that it is within the daya you want to sort, and

问题 I'm trying to write a function that would sort a collection of objects. Since the objects are all of the same type (the same user-defined class), their property set is the same. Is it possible to discover the object's properties (through code) so as to put the collection in a bi-dimensional array, each row being for an object, each column for one of its property? Another solution would be to copy each object from the collection to an array of objects, and sort them by one of their property,

问题 function void sortDynamicData(typeOfClass,SortKey) { List<dynamic> results = null; //results might be of any type it may contain students data or books data or professors data, hence I took as dynamic results = services.GetMyresults(typeOfClass); //returns list of dynamic objects results = results.OrderBy(SortKey).ToList(); ... ... ... } my question is I want to sort the results based on sortKey Any help would be greatly appreciable. 回答1: If possible, I think it's better and easier to work

问题 I am working on a sorting project and I've come to the point where a main bottleneck is reading in the data. It takes my program about 20 seconds to sort 100,000,000 integers read in from stdin using cin and std::ios::sync_with_stdio(false); but it turns out that 10 of those seconds is reading in the data to sort. We do know how many integers we will be reading in (the count is at the top of the file we need to sort). How can I make this faster? I know it's possible because a student in a

问题 In the following Python script where "aDict" is a dictionary, what does "_: _[0]" do in the lambda function? sorted(aDict.items(), key=lambda _: _[0]) 回答1: Lets pick that apart. 1) Suppose you have a dict, di: di={'one': 1, 'two': 2, 'three': 3} 2) Now suppose you want each of its key, value pairs: >>> di.items() [('three', 3), ('two', 2), ('one', 1)] 3) Now you want to sort them (since dicts are unordered): >>> sorted(di.items()) [('one', 1), ('three', 3), ('two', 2)] Notice that the tuples

问题 This question already has answers here : Sort array of strings by integer (which is the first character) (3 answers) Sort Array Elements (string with numbers), natural sort (8 answers) Closed 2 years ago . Below is an example of my array of objects and I am supposed to sort these by name. The js normal sorting sorts as shown below, however my target is to sort by the numeric value, eg: "1 ex, 2 ex, 3 ex, 4 ex, 11 ex ..". Could someone help me how to achieve this? [{id: 588, name: "1 ex"} {id:
