Given a vector of lengths [a b c], determines whether a triangle with non-zero area (in two-dimensional Euclidean space, smarty!) could have sides of those lengths.
[1 2 1000] ---> false
[3 4 5] ---> true
[5 5 5] ---> true
Tests with sides that are not sorted should be added.
I wanted to try out the Hankel here. This is more than necessary. It checks to see that the sum of all pairs of sides are greater than the remaining side. You really only need to do this to compare against the maximum length side.
This is just bad, only gaming the test suit. There is nothing to be learned from this.
worst solution ,i have ever seen
Added to test suite to eliminate this "solution".
Return the largest number that is adjacent to a zero
Most nonzero elements in row
Number of Horns on a unicorn!
Cull vector elements that contain a specified digit
Sum my indices
Maintain shape of logical-index mask
Is my wife right?
So many choices
