No problem.

To create a file, delete a file or rename a file you need write permission
for the directory that it is in.  To modify file you need write
permission for the file itself.

It's the same as "cat <answers >answers2" but in a different order: the
cat program copies its standard input to its output, with the input
redirected from answers and the output redirected to answers#2.
