Answer 1

import scala.util.matching.Regex

object PhoneNumberValidation extends App {
  val phoneNumbers = Seq(
    "333-555-1234",
    "(333)-555-1234",
    "333 555 1234",
    "333.555.1234",
    "+91 (333) 555-1234"
  )

  val pattern: Regex = """^(\+\d{1,2}\s)?\(?\d{3}\)?[\s.-]?\d{3}[\s.-]?\d{4}$""".r

  phoneNumbers.foreach { phoneNumber =>
    if (pattern.matches(phoneNumber)) {
      println("Valid phone number format")
    } else {
      println("Invalid phone number format")
    }
  }
}
