问题 One parameter in my model controls the dimension of arrays; it can vary from 1 to any positive integer: for my purposes this can be up to 20. The flow of the program goes through a number of loops that depend on this dimension. For example, if the value of the parameter is one I would have: for i1 in range(0,100,1): do stuff If the value of the parameter is two, then I would have something like: for i1 in range (0,100,1): for i2 in range (0,100,1): do stuff Or, if the value of the parameter

问题 In VB.NET 2010, How would one go about creating a list of Parent classes where each Parent has it's own list of Child classes. Where the list of child classes could be as few as 1 child or as many as a few hundred child objects? 回答1: Dim ChildList as generic.list(of object) Dim ParentList as generic.list(of ChildList) You can do it like above 回答2: Sounds like you need a LinkedList object: LinkedList Outer; where ParentType is a class that has another LinkedList object of it own: Public Class

问题 Hi, I wanted to store key and value of a nested Map that looks like this: Map<ArrayList <String>, Map<String, Integer>> NestedMap = new HashMap<ArrayList<String>, Map<String, Integer>(); into another variable let say getKeyFromInsideMap and getValueFromInsideMap. So it would be the values of the inside Map String and Integer that am interested in accessing. How do I this in a code? I tried several examples here in the forum but I don't know how the syntax would look like. Could you please

问题 Can't find a question similar to what I am trying to do. I have a workhorse function that can take any of a class of custom-made sub-functions, with their respective arguments, and do certain processing on it, like the following toy examples: func1 <- function(a, b, c) {a + b * c} func2 <- function(x, y, z, bob, bleb) {(x / y)^bleb * z/bob} workhorse <- function(m, n, o, FUN, ...) { result <- FUN(x, y, ...) [process result with m, n, and o] } By itself, this works perfectly well as intended,

问题 I'm trying to implement a nested TabbedViewNavigator (inside a View). I did this by following method 3 described in this post: Flex - how to make a tabbed panel Code here: <s:View xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" title="HomeView"> <s:TabbedViewNavigator width="100%" height="100%"> <s:ViewNavigator label="1st Tab" width="100%" height="100%" firstView="views.FirstTabView"/> <s:ViewNavigator label="2nd Tab" width="100%" height="100%" firstView=

问题 How should I convert a series of nested hashes (nested to arbitrary depth) to a series of nested OpenStructs? I'm loading in a big YAML file and I'm not enjoying accessing['everything']['like']['this'] . I have found a few partial solutions using Google, but I thought this would make a nice question here. Here is one of the solutions I found from http://andreapavoni.com/blog/2013/4/create-recursive-openstruct-from-a-ruby-hash: # deep_struct.rb require 'ostruct' class DeepStruct < OpenStruct

问题 I would like to know how can I iterate in a 2Dimensional HashMap? I am creating an Object TrueStringMap2D that does the following: It will be a map 2D, i mean 2 keys and one value. But the iterator implemented here is not functional.. i didnt know how to redefine the Iterator method in TrueStringMap2D :S (if possible should be remove in the iterator() functional) Anyone can help? Thankyou very much!! 回答1: I'll reinterpret the question into something similar that I enjoy answering, and then

问题 I have data that, in a "normal" query, would appear like this: Val1 Val2 ---- ---- 1 2 2 [blank] 3 2 4 5 1 6 3 .. 96 1 What I want, though, is something like this (I need to limit the number of rows to 12): Val1 Val2 Val1 Val2 Val1 Val2 ... Val1 Val2 ---- ---- ---- ---- ---- ---- 1 2 13 1 25 [blank] ... 85 1 2 [blank] 14 1 26 3 ... 86 [blank] .. ... ... ... ... ... ... ... ... 12 1 24 [blank] 36 2 ... 96 3 Is there a select statement that would give me that? I'm no SQL expert, but I'm
