I am having trouble understanding the concept, for e.g - tril(magic(10)), what I understand is 92+98+81+87+93+76+89+97+78+84=875, which is incorrect acc to the test suite

This solution together with the solution of James' (or mine) exhibits a nice duality between the "top-down" and "bottom-up" approaches.

Nice! When you go from the bottom, solution automatically goes to a(1).

Thanks. I coded that solution up LONG before movmax became a thing...
