Problem 7. Column Removal

Dear Oscar,
in comparison to your code, the below implementation is much faster but your style of code is a crack to cody system, well done.

function A = column_removal(A,n)
A(:,n) = '';
end

Dear Sadid, I agree with you that my implementation is completely stupid and a waste of time in real life and that's why I don't like the current evaluation metric of Cody. A (time and/or memory)-based evaluation would be much more interesting. With the current evaluation metric, Cody promotes hacking and cracking (which is also fine), but players don't learn good manners for developing efficient code.
