In Haskell, some matrices aren't even matrices. There are rows with different lengths.

You are missing the fact that the kata is not about a regular binary encoding, but about BCD encoding. Youl need to look up what BCD is and how it works.

Am I missing something? The test case 10 == 0001 0000 doesn't make any sense. The Decimal number 10 == 0000 1010 (1(8) + 0(4) + 1(2) + (0)1).

• Ruby 3.0 should be enabled (locked in)

• Sample tests should use assert_equals or even better Rspecs's expect
