ed is the standard text editor on Unix systems. Your goal is to write an ed clone.
Write a program that reads an input stream and for every received end of line character, print
? followed by a end of line character.
- The communication has to interactive. Means the program needs to output as soon as possible and has to accept more input after that.
- There are no input lines that are longer than 105 characters + end of line character
- You can choose which character or sequence you use as end of line character, as long as it does not contain any alphanumerical characters nor the
- The program should not output anything else.
Shortest code wins.
Example Python Script
#/usr/bin/env python3 import sys for line in sys.stdin: print("?")
