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

object Last30Days {
  def main(args: Array[String]): Unit = {
    // Get today's date
    val today = LocalDate.now()

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

    // Create an array to store the full dates
    val dates = Array.ofDim[String](30)

    // Populate the array with the last 30 full dates
    for (i <- dates.indices) {
      val pastDate = today.minusDays(i) // Subtract 'i' days
      dates(i) = pastDate.format(formatter) // Format the date and store it
    }

    println("Dates:")
    for (date <- dates) {
      println(date)
    }
  }
}
