Kas on Dispatchers.Default Kotlinis ja kuidas seda kasutatakse?

Dispatchers.Default in Kotlin is the default coroutine dispatcher, designed to execute CPU-intensive tasks in an optimized thread pool for parallel work.

When to use Dispatchers.Default:

• For operations requiring intensive calculations (e.g., data processing, complex algorithms).
• When you do not want to block the main thread (UI) and want to efficiently utilize CPU resources.

Example of usage:

import kotlinx.coroutines.*

fun main() = runBlocking {
    launch(Dispatchers.Default) {
        // CPU-intensive task
        val result = (1..1_000_000).sum()
        println("Sum: $result")
    }
}

This way, Dispatchers.Default helps to efficiently distribute computational tasks among threads without blocking the application's main thread.
