Save your work in a file called regexlab.scala. Use this template:
import scala.util.matching.Regex
object RegexLab {
def negate_alphanumeric: Regex = """<your regex>""".r
def email: Regex = """<your regex>""".r
def real_numbers: Regex = """<your regex>""".r
def landlines: Regex = """<your regex>""".r
def name: Regex = """<your regex>""".r
def all_vowels: Regex = """<your regex>""".r
def string_in_singleline_comment:Regex = """<your regex>""".r
}Your task is to define the regular expression for the following attributes. For all the methods defined above:
yourregex.findAllIn(str).toList must return all the matches found.
