It should be noted that spaces should be ignored or else test suites 3 and 5 fail.
good use of 'hankel' function
Sorry about this, but I got stuck and I want to learn how to do it. After looking at several solutions, I found my mistake and was able to create my own solution :)
What happens if the test suite changed in the future?
This solution is not correct in general, as the way of using hankel here, generates n-1 fake fragments
Clever usage of the Hankel matrix. I don't automatically think of the Hankel for this application, but it really works well. Thanks - I've learned something
What's the point of a 'solution' like this? It passes the test suite, but in what way was it interesting for you to write it?
Find best placement for ordered dominoes (harder)
Is A the inverse of B?
Find the hypotenuse
Area of an equilateral triangle
Is this is a Tic Tac Toe X Win?
Find all elements less than 0 or greater than 10 and replace them with NaN
Find relatively common elements in matrix rows
