I am not able to figure out why the solutions of my code to test 8 and 9 are wrong.
My wrong results:
- test 8 -> '1250000041666667776'
- test 9 -> '13107200170666672128'
I get precisely the same results as Angelo...
Angelo and Heiko, your solutions are working to a degree. However to obtain exact results on big numbers you have to use different tools. You can search for uint64 and bigdecimal. Hope it helps.
Thanks for the tip with uint64.

First line is adopted from James's solution: https://www.mathworks.com/matlabcentral/cody/problems/2455-diagonal-of-a-spiral-matrix/solutions/1239477
I was just happy I could use "diag" and "spiral" in this problem, but it's always nice to see some of my solutions get used in other code.
