Code:

    var c1:Int=1;
    launch (Dispatchers.Default){ while (c1<10){
        c1++;
        val deferred1 = async { tic("tick") }
        val deferred2 = async { tic("tok") }.await()
    } }
    println("main thread end")
}
suspend fun tic(startNum: String){
    delay(1000)
    println(startNum)
}


output :
