There's an expression.
```
1/30 
```
How do you round the results to a whole number? For example, there is a number 1

For example,
```
Math.Ceiling(1.0/30.0)
```
Don't forget that you're using a countless division. The result of the 1/30 is zero. So go to the split of the rubber chips (1.0/30.0 = 0.0333333333...) and this number is rounded up.

In the following article, I will change the way of thinking of reList. https://ja.stackoverflow.com/q/35963/26370 The following: The argument name of the line number was changed to srcno, dstno.static Dictionary<int, string> ChangeOrder(Dictionary<int, string> oldDictionary, int srcno, int dstno) { // 行番号の範囲チェックが必要ならばこの場所で行う。 // 元のDictionaryの値をkey(行番号)でソートしてリスト化 List<string> valuelist = new List<string>(); foreach (var d in oldDictionary.OrderBy((e) => e.Key)) { valuelist.Add(d.Value); } // 行番号1オリジンをリストインデックス0オリジンに変換 srcno--; dstno--; // リストによる位置の入れ替え string temp = valuelist[srcno]; valuelist.RemoveAt(srcno); valuelist.Insert(dstno, temp); // 新しいDictionaryの作成 Dictionary<int, string> newDictionary = new Dictionary<int, string>(); int key = 1; // keyは1オリジン foreach (string s in valuelist) { newDictionary.Add(key++, s); } return newDictionary; }

I'm not sure I got the task right, because I've got 42 on this sequence. But I'll write the answer just in case.The general idea of my algorithm is to go through the cycle with all the sequence, going to the classroom for the rest of it whenever the current element does not complete another combination. If the current element is final, then a unit is added to the intermediate outcome. Each challenge reverts its intermediate outcome, which is added to the intermediate outcome of the higher level. And at the end, the merging of the intermediate outcomes of the first level gives the total number of combinations.On Python, it looks like this:#!/usr/bin/python numbers = [2, 9, 3, 6, 3, 8, 1, 10, 6, 7] def combinations(selected=[], nexts=numbers): subtotal = 0 for i, n in enumerate(nexts): if sum(selected) + n > 8: # print selected+[n] subtotal += 1 else: subtotal += combinations(selected+[n], nexts[i+1:]) return subtotal print combinations()

You have several mistakes in that code. I will correct some, but not all, especially the object of the account that should have builder, methods that make certain operations rather than accessing the data directly. And I didn't treat mistakes properly, just not letting it happen.I gave a better name for what is the object that is trying to treat. And using the correct type to handle monetary value.I test if the typed data makes sense and only accept it when it is ok. The way it was breaking the application by a wrong typing.I gave more significant names for all variables.When I ask yes or no I ask for a normal text, because leaving only one key set what it will do may not be a good IU. Actually I wouldn't even ask that, I would ask for the value and accept 0, but I didn't take it to show how it corrects the value.ReadKey() does not do what you expect, it does not return a text or a number that makes sense as text, it returns the key code, and not a code of a character.And you can't declare a variable conditionally.using static System.Console; using System; namespace Projeto { public class Program { public static void Main() { Conta conta = new Conta(); Write("Entre com o numero da conta: "); if (!int.TryParse(ReadLine(), out var numero)) return; conta.Numero = numero; WriteLine(); Write("Entre com o nome: "); conta.Nome = ReadLine(); WriteLine(); Write("Haverá um deposito inicial (s/n)? : "); var temDeposito = ReadLine(); var valor = 0M; if (temDeposito.Equals("S", StringComparison.CurrentCultureIgnoreCase)) { Write("Entre com o valor depositado: "); if (!decimal.TryParse(ReadLine(), out valor)) return; } conta.Saldo = valor; } } public class Conta { public int Numero { get; set; } public string Nome { get; set; } public decimal Saldo { get; set; } } } See https://ideone.com/r7c6yH . And https://dotnetfiddle.net/81SLn3 . Also https://github.com/maniero/SOpt/blob/master/CSharp/Console/ReadKeyLine.cs .

One option:Take a separate set with zero elements and increase per unit the value retained by the equal value index of the element of the reference matrix. Then remove all elements with values below 2.The last remaining volume index will be the required value.

unsigned long long p(int n) { if (n < 0) return 0; if (n <= 1) return 1; unsigned long long sum = 0; for(int k = 1, s = 1; (3*k-1)*k/2 <= n; ++k) { int l = (3*k+1)*k/2; int m = (3*k-1)*k/2; sum += s*(p(n-l)+p(n-m)); s = -s; } return sum; } This is if the number is included (a sum of one decomposition). If you don't turn it on, well, you'll have to count the unit.A clue: Knut, "Programming art"volume 4A.

Suppose you have an empty Asp.Net MVC project where you selected the Individual User Accounts when you were created. It's quite a job job that already has an entrance to the login room, examples of pages with submissions. Let's start with her.Check that you have a user model:// You can add profile data for the user by adding more properties to your ApplicationUser class, please visit https://go.microsoft.com/fwlink/?LinkID=317594 to learn more. public class ApplicationUser : IdentityUser { public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager) { // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie); // Add custom user claims here return userIdentity; } } And make a model for books:public class Book { public int ID { get; set; } public string Title { get; set; } } The first thing we need is to create it. https://metanit.com/sharp/entityframework/3.7.php between Book and ApplicationUser (one book may have only one user(s), one user may have many books). This is the moment for the Entity Framework, learn it carefully, as it is the basis on which more complex things are built.In the Book, add: public int OwnerId { get; set; } [ForeignKey("OwnerId")] public virtual ApplicationUser Owner { get; set; } In the applicationUser class, add: public virtual ICollection<Book> Books { get; set; } And don't forget to add to the ApplicationDbContext. public DbSet<Book> Book { get; set; } (This is a good time to apply migration-- Add-Migration CreateBookTable♪ Update-Database but may not be usedIn principle, that's it. You can create the counter-allers and the things you want.Let's say for simplicity, you have some basic controller to be more comfortable with the base:public class BaseController : Controller { public BaseController() { this.DbContext = new ApplicationDbContext(); } protected ApplicationDbContext DbContext { get; } } And you only want to show some particular user's books. Controller:public class BookController : BaseController { public ActionResult GetUserBook(int ownerID) { var books = this.DbContext.Book .Where(x => x.OwnerId == ownerID) .ToArray(); return View(books); } } Introduction:@model WebApplication1.Models.Book[] <h2>title</h2> @foreach (var book in Model) { @book.Title<br> } Or if you want everyone to see only their books: public ActionResult MyBooks() { if (!this.User.Identity.IsAuthenticated) return this.Redirect("/"); var books = this.DbContext.Book .Where(x => x.OwnerId == this.User.Identity.GetUserId<int>()) .ToArray(); return View(books); } I'm recommending this. Microsoft's default for a user model offers a primary key in the form of a line... However, sometimes it's easier to work with int - so you can practice separately in a type change for UserId. Here. https://docs.microsoft.com/en-us/aspnet/identity/overview/extensibility/change-primary-key-for-users-in-aspnet-identity On this subject.The example that I've brought - the training, is that it's got a lot of things to do. Let's just say it's easier to check the authorisation: [Authorize] public ActionResult MyBooks() { var books = this.DbContext.Book .Where(x => x.OwnerId == this.User.Identity.GetUserId<int>()) .ToArray(); return View(books); } We can separate the domen from the data layer. But you've got enough trivial example to do.

You can use a singlton.

"Chile" with a point-- text, mathematical transactions with such data would make a mistake. We need to get the data to the same type. Sub Sum_() Dim aData() Dim dSum As Double Dim i As Long With ActiveSheet ' если нужно, указать другой лист' i = .Cells(.Rows.count, 1).End(xlUp).Row aData = .Range("A1:B" & i).Value For i = 1 To UBound(aData) aData(i, 1) = Replace(aData(i, 1), ".", ",") aData(i, 2) = Replace(aData(i, 2), ".", ",") dSum = dSum + aData(i, 1) * aData(i, 2) Next i .Cells(1, 3).Value = dSum End With End Sub The data is better stored in odiac formats.Give a data range, Ctrl+H♪ Hey. Right. CHANGE to the comma, Okay.♪Normal data and macroes need not:=СУММПРОИЗВ(A1:A100;B1:B100)

If there are many elements, it's a collection/massiv.If the collection changes (emergence/emergence of elements BindingList or ObservableCollectionbecause they have implementation INotifyCollectionChanged♪If the collection is static, you can use the mass.On this basis, you can make the following:Set up a collection:public ObservableCollection<ViewModel> Items { get; } ViewModel - it's your class with the characteristics of the button.get; - we really need to get the only elements out of it without initializing it all the time. set;♪Initiate the collection and complete.public MainViewModel() { Items = new ObservableCollection<ViewModel> { new ViewModel() //Задаем нужные свойства если надо. }; } You can write at any time. Items.Add(...)♪We'll redesign XAML:Change <Canvas> <Button x:Name="button1" Width="41" Height="38" Opacity="1" Command="{Binding ToggleCommand}" Canvas.Left="150" Canvas.Top="146"> <Image x:Name="Qwe1" Style="{StaticResource ResourceKey=image}" Width="41" Height="37"/> </Button> <Button x:Name="button2" Width="41" Height="38" Opacity="1" Command="{Binding ToggleCommand}" Canvas.Left="100" Canvas.Top="146"> <Image x:Name="Qwe2" Style="{StaticResource ResourceKey=image}" Width="41" Height="37"/> </Button> <Button x:Name="button3" Width="41" Height="38" Opacity="1" Command="{Binding ToggleCommand}" Canvas.Left="200" Canvas.Top="146"> <Image x:Name="Qwe3" Style="{StaticResource ResourceKey=image}" Width="41" Height="37"/> </Button> </Canvas> Here.<ItemsControl ItemsSource="{Binding Items}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapPanel/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <Button Width="41" Height="38" Command="{Binding ToggleCommand}"> <Image Style="{StaticResource ResourceKey=image}" Width="41" Height="37"/> </Button> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> It's as you can see, it's being used.

Your youth tests should not be connected to the database at all. You should only test your validation class, all the external dependence of this class should be replaced by mos. You've got to have a bow that's gonna pretend he's connected to the database, but it's not really going anywhere, but just returning the right things to test.Like one test. Let's just say you're checking that there are no two elements in the database with the same id. Then the test should look like,creates class mocks to access the databaseYou're building the right method of this mok so he can retrieve. You're transferring this poppy to the validator, and you're convinced Validation didn't pass.The code is about this (in the example) https://ru.wikipedia.org/wiki/NUnit and https://github.com/Moq/moq4 [Test] public void Test1() { // arrange var dbRepositoryMock = new Mock<IDbReposiitory>(); dbRepositoryMock.Setup(x => x.GetItems()).Returns(new [] {new Item(){ Id = 1}, new Item(){ Id = 1}}); var validator = new Validator(); // action var validationResult = validator.ValidateItemsUnique(dbRepositoryMock.Object); // assert Assert.IsFalse(validationResult); } I mean, that's the idea, you're creating a real copy of TALK for a test class. In our case, the test class is the lead. For all your addictions, you're making moks, and you're putting those moks on the TV that use a testable function, everyone else just ignores. For example, your repository may have 20 more methods that retrieve different identities from the database, but if you check the uniqueness of the Items, you only set back the value of the method. GetItems()and all the other methods just ignore.Forget about connecting to the database at all, your tests must be done without it. If it's hard for you to write a code in that style, without a real connection to the database, it's badly adapted to the test, and it needs to be re-activated.Your attempt to write a youth test with a connection to the real bed is a pretty typical mistake for starters to write the test. I tried to do that, too, and I saw what others were trying to do. This mistake indicates you don't understand. meaning You should spend some time reading a book on this subject. Kent Beck's test run. It'll be a great option.

The addition of the loss will not send the form if the data do not correspond to the template.But it's just the tip of the iceberg.You're supposed to have to approach the data validation more tightly, and the limit to the max length/col-wheel is just the beginning. ♪ ♪I don't know what to say about it, it depends on the task and the tools you use.For jQuery, you can look at it. http://jqueryvalidation.org/minlength-method (Sam wasn't used).In Angular, regular resources are available.Someone writes their decisions.Someone's got a second option. UPD3Try something like:$('input.maxlimit').keydown(function(){ var max = $(this).data('max'); var keyCode = event.keyCode; if( keyCode!=8 && keyCode!=46 && this.value.length==max ) this.value = this.value.slice(0,-1) console.log(keyCode); /// OR alert(keyCode); }); 8 - backspace, 46 - delete as I don't know.Get the right codes with the console or the same alerta.
