   1: WRITELN echo 123 > 1.txt
   2: WRITELN head < 1.txt
   3: WRITELN diff -y - 1.txt < 1.txt

Your answer may be identical to the JOJ answer in the first several lines.

However, you will still get Wrong Answer because the complete output may be longer and there might be errors in the future lines.

Please double check your code to solve this problem and try again.
