Scala

import scala.io.Source

object SplitPhoneNumber extends App {

  private[this] val SPLIT_PATTERN = " |\\-"

  val numbers = Source.stdin.getLines().drop(1)

  numbers.foreach(num => {
    val splits = num.split(SPLIT_PATTERN)
    println(s"CountryCode=${splits(0)},LocalAreaCode=${splits(1)},Number=${splits(2)}")
  })
}

val numbers = Source.stdin.getLines().drop(1)

numbers.foreach(num => {

val splits = num.split(SPLIT_PATTERN)

println(s"CountryCode=${splits(0)},LocalAreaCode=${splits(1)},Number=${splits(2)}")

})

}

Java

import java.util.*;

    public static void main(String[] args) {
        Scanner stdin = new Scanner(System.in);
        int tests = Integer.parseInt(stdin.nextLine());

            String[] splits = stdin.nextLine().split(" |\\-");
            System.out.println("CountryCode=" + splits[0]
                    + ",LocalAreaCode=" + splits[1] + ",Number=" + splits[2]);
        }
        stdin.close();
    }
}

String[] splits = stdin.nextLine().split(" |\\-");

System.out.println("CountryCode=" + splits[0]

stdin.close();

JavaScript

    let numbers = input.split('\n').slice(1);
    for(let i = 0; i < numbers.length; i++) {
        let splits = numbers[i].split(/ |\-/);
        console.log("CountryCode=" + splits[0]
            + ",LocalAreaCode=" + splits[1] + ",Number=" + splits[2]);
    }
};

process.stdin.resume();
process.stdin.setEncoding("ascii");

var _input = "";
process.stdin.on("data", input => _input += input);
process.stdin.on("end", () => processData(_input));

'use strict';

const processData = input => {

let numbers = input.split('\n').slice(1);

}

};

process.stdin.resume();

process.stdin.setEncoding("ascii");

var _input = "";

process.stdin.on("data", input => _input += input);

process.stdin.on("end", () => processData(_input));

Ruby

tests = gets.chomp.to_i
tests.times do
  (country_code, local_area, number) = gets.chomp.split(/ |\-/)
  puts "CountryCode=#{country_code},LocalAreaCode=#{local_area},Number=#{number}"
end

tests = gets.chomp.to_i

tests.times do

(country_code, local_area, number) = gets.chomp.split(/ |\-/)

puts "CountryCode=#{country_code},LocalAreaCode=#{local_area},Number=#{number}"

end
