• not enough tests
• needs random tests
• needs to test edge cases more precisly (especially about the order in which the "oddities" have to be resolved)
• you didn't make clear how we're supposed to identify when 1 hour has to be deduced for lunch (not hard to get, yes, but that should be in the description)

Hi,

The rules are somewhat unspecified about this case:

[['8:30', '17:30'],
[],
['8:30', '13:30', '14:00'],
['8:00', '17:00'],
['8:30', '13:00', '15:00', '17:30']]

you expect "... missed one day" while one could considere return the "odd" thing instead. => you have to tell how the check should be done:

• return the first encountered error?
• check for one specific kind first?
