public class Solution { public static void main(String[] args) throws Exception { //InputStreamReader in = new InputStreamReader(System.in); BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); // /InputStream inStream = new FileInputStream(reader.readLine()); BufferedInputStream buffer = new BufferedInputStream(new FileInputStream(reader.readLine())); //while(buffer.available() > 0){ while(buffer.ready()){ char c = (char)buffer.read(); System.out.print(c); } reader.close(); //inStream.close(); buffer.close(); } }
