PLEASE USE JAVA:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.nio.charset.StandardCharsets;

public class Main {
/**
* Iterate through each line of input.
*/
public static void main(String[] args) throws IOException {
InputStreamReader reader = new InputStreamReader(System.in, StandardCharsets.UTF_8);
BufferedReader in = new BufferedReader(reader);
String line;
while ((line = in.readLine()) != null) {

///CODE GOES HERE

System.out.println(line);
}
}
}
