Sort means ascending or descending or both? Not clear
I agree! The code is significantly different for those possible cases.
Unfortunately, way too easy!
I agree it's not clear ... but
y = ~var(nonzeros(sign(diff(x))));
works for both ascending/descending cases.
(The test suite clarifies that ascending is the intended case)
y = ~var(nonzeros(sign(diff(x)))); amazing~ !nice idea
There is a sort array command in MATLAB.
if you are not familiar with array, will be difficult
nice
hehe
The solution "y = issorted(x);" with a metric of 12 is not the leading solution. "Fair Play" is something unknown to cheaters!
