import java.time.LocalDate
import java.time.format.DateTimeFormatter

fun getLast30Dates(): Array<String> {
    // Get today's date
    val today = LocalDate.now()

    // Define the date formatter
    val formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd")

    // Create an array to store the last 30 dates
    val dates = Array(30) { i ->
        today.minusDays(i.toLong()).format(formatter)
    }

    return dates
}

fun main() {
    // Get the last 30 dates by calling the function
    val dates = getLast30Dates()

    println("Dates:")
    for (date in dates) {
        println(date)
    }
}
