🖥 Задача: Что выведет этот код на C\#?


using System;
using System.Threading.Tasks;

class Program
{
static async Task Main(string[] args)
{
Console.WriteLine("1");
var task = FooAsync();
Console.WriteLine("2");
await task;
Console.WriteLine("5");
}

static async Task FooAsync()
{
Console.WriteLine("3");
await Task.Delay(100);
Console.WriteLine("4");
}
}


Вопрос:
Какой порядок чисел появится в консоли?

👇 Подумай, прежде чем смотреть ответ.



Разбор:

1. Console.WriteLine("1"); → печатает 1

2. var task = FooAsync(); → вызывается FooAsync(), который:

печатает 3

доходит до await Task.Delay(100); и возвращает управление в Main (не дожидаясь задержки)

3. Console.WriteLine("2"); → печатает 2

4. await task; → теперь Main ждёт завершения FooAsync

5. после 100ms продолжает выполнение в FooAsync → печатает 4

6. возвращаемся в Main → печатает 5



🎉 Окончательный вывод:

1
3
2
4
5

📝 Что проверяет задача:

- Понимание работы async/await

- Как работают точки приостановки (suspension points)

- Когда код возвращается в вызывающий метод

Export WhatsApp stickers to Telegram on Android

From the Files app, scroll down to Internal storage, and tap on WhatsApp. Once you’re there, go to Media and then WhatsApp Stickers. Don’t be surprised if you find a large number of files in that folder—it holds your personal collection of stickers and every one you’ve ever received. Even the bad ones.Tap the three dots in the top right corner of your screen to Select all. If you want to trim the fat and grab only the best of the best, this is the perfect time to do so: choose the ones you want to export by long-pressing one file to activate selection mode, and then tapping on the rest. Once you’re done, hit the Share button (that “less than”-like symbol at the top of your screen). If you have a big collection—more than 500 stickers, for example—it’s possible that nothing will happen when you tap the Share button. Be patient—your phone’s just struggling with a heavy load.On the menu that pops from the bottom of the screen, choose Telegram, and then select the chat named Saved messages. This is a chat only you can see, and it will serve as your sticker bank. Unlike WhatsApp, Telegram doesn’t store your favorite stickers in a quick-access reservoir right beside the typing field, but you’ll be able to snatch them out of your Saved messages chat and forward them to any of your Telegram contacts. This also means you won’t have a quick way to save incoming stickers like you did on WhatsApp, so you’ll have to forward them from one chat to the other.

Look for Channels Online

You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit. This is one of the biggest sites on the internet, with millions of communities, including those from Telegram.Then, you can search one of the many dedicated websites for Telegram channel searching. One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels. If you want to join a private channel, you’ll have to ask one of its members to invite you.
