I tried. But caught with error.

it is very easy to abuse the solution map by writing a correct solution with a lot of useless code before it. I tested this and got the solution map rescaled to absurdity (and I see I'm not the only one). Please correct this.

What is wrong with this solution?
Alex Buczynsky
on 9 Oct 2016
the code is wrong because the function name should be 'add_two_numbers'.
In the test code the are evaluating:
assert(isequal(add_two_numbers(a,b),c_correct))
So if your function is called 'sum' it wont be called by the test script.

Try writing out the equation you want to use, with 'c =' on the left, and 'a' and 'b' on the right. You don't need to define c =.., a =.., or b =.. in the function.
Good luck!

hello brian !
I'd like to know how your solution size is 9.
Can you please let me know how you did it ?
Thanks !

Why is this of size 9? The long string?
Brian Moore

For the record, I don't recommend reading this, but here goes:
My solution is
function ans = add_two_numbers(varargin)
system 'echo "function ans = assert(~), true;" > ./assert.m';
It works by redefining the assert() function that the test suite uses to always return true. This strategy can be used to solve any problem. Many of the leading solutions to problems are hacks like this. It's actually quite fascinating to think of ways to "cheat" the system

Ah, that makes so much more sense! Thanks for explaining Brian.

Why is the following not accepted ?
add_two_numbers = @(x,y) x+y;
Solution size is also 9, but the solution is not recognized. Just wondering why, as it works in MATLAB.

@Danilo Maybe the website prevents anonymous functions.

It was a system error. I re-scored the solution, and that did the right thing.

Of course, c = a+b; is entirely correct, using the operator form for addition. plus(a,b) uses the function form.
