Thanks!

Unfortunately both solutions there failed one or more of the tests.
The first (larger in lines of code) failed on these:

    items = [ 2,2 ]
    rows = [ [1,2], [2,3] ]

    items = [ 1,2,2 ]
    rows = [ [1,2], [1,2], [1,3] ]

The second failed on just the latter dataset, above.  (And both
failed on my larger 'benchmark' dataset...)


. . . Those unit tests are merciless, huh?  :-)
