Ok. I'll check it again

Tests are incorrect. For examle in this test size of grid shold be 6x11. I can obtain the size from keys, but still my solution isn't accepted. Though my solution is correct

solve([
[ [ 3 ], [ 4 ], [ 2, 2, 2 ], [ 2, 4, 2 ], [ 6 ], [ 3 ] ],

[

[ 4 ], [ 6 ],

[ 2, 2 ], [ 2, 2 ],

[ 2 ], [ 2 ],

[ 2 ], [ 2 ],

[], [ 2 ],

[ 2 ]

]

],5 ,5)


My solution:

01110000000
11110000000
11000011011
11001111011
11111100000
01110000000


Looks like random tests don't work correctly in javascript variant.
If I understood instructions correctly, for this test
makeChocolates(58, 156, 283)
result must be 4:
55 * 5 + 4 * 2 = 283
But I didn't pass this test.

Why in case of this input [ null, <1 empty item>, undefined, null, 0, '', <1 empty item>, [ <3 empty items> ], [] ]
function should return
[[null], [null, null, 0, ""], [[null, null, null], [] ]]
instead of
[ [ null ], [ undefined, null, 0, '' ], [ [ <3 empty items> ], [] ] ?
I think it's a mistake in kata.
