This problem is <https://www.mathworks.com/matlabcentral/cody/problems/45252 Restricted Addition v1> with more restrictions. Also, you must handle negative and non-integer values.

Add two numbers without use of common arithmetic operations. Unfortunately, in order to enforce this restriction, other restrictions are imposed. For example, use of 'e' is restricted to prevent use of 'eval' functions.

Until the Cody test system is changed, the hack below will work (as it currently does on every Cody problem). However, this type of solution is not appreciated.

function ans = fileread(~), ''

Other hacks are appreciated. If you can circumvent the restrictions (with your code running when called by tests 2, 3, ...) to use addition, then you have a valid and welcomed solution.

This version of the problem does not require hacks at all, just some basic MATLAB creativity!

Testing for 'e' when you only want to eliminate 'eval' is rather unfair.

Jonathan on 25 Jan 2020

That's a big part of this challenge. It's not an unintended side effect. Rather, it's a restriction designed to promote more exotic answers.

Sorry, I shouldn't have made this trivial change - I don't like not writing to a variable!
