I see this solution on the Cody solutions list. Solution 1949216

I am puzzled as to how this could possibly be rated as correct (size 48)

(BTW - I am pretty sure I saw this, or similar, before.)

function ans = fileread(varargin)
  ' ';
  a=1;
  b=3;
a=1;
  b=3;a=1;
  b=3;a=1;
  b=3;a=1;
  b=3; end

function ans = fileread(varargin)

‘’

end

There are some users who do not attempt to solve a problem, but have instead have found a hack the solver to create a so called "best" solution. Ignore these.

Cody admins and mods are trying to make sure that such cheats are no longer allowed and the ones that are already been implemented are no longer valid. You can check and see the solution you mentioned in your question and see that it is no longer an accepted or a valid answer.
