package com.example

import kotlinx.coroutines.*
import kotlinx.coroutines.channels.Channel
import kotlin.random.Random

fun main(){
    val channel = Channel<Int>(2)
    runBlocking {
        launch { produceValue(channel, 5) }
        launch { consumeValue(channel, 5) }
    }
}

suspend fun produceValue(channel: Channel<Int>, idx: Int) {
    for (i in 1..idx) {
        val number = Random.nextInt()
        println("$i: Sending $number")
        channel.send(number)
    }
}

suspend fun consumeValue(channel: Channel<Int>, idx: Int) {
    for (i in 1..idx) {
        delay(500)
        println("$i: Received ${channel.receive()}")
    }
