Line 34:
Good question, and that "determine if" thematic framing of the task inevitably produces clear expectations of a String -> Bool predicate, returning True or False for a given string.
That expectation is then lead completely astray into open fields, where no mention of any kind of test or predicate can actually be found in the detail of the sub-tasks. [[User:Hout|Hout]] ([[User talk:Hout|talk]]) 14:39, 8 June 2020 (UTC)
To put it another way, the title suggests writing an testing something like this:
<pre>containsConsecutivelyRepeatedCharacters :: String -> Bool
containsConsecutivelyRepeatedCharacters = (>) . length <*> (length . group)</pre>
and the tasks describe something quite different. A (String -> String) function which defines a new string but 'determines' nothing. [[User:Hout|Hout]] ([[User talk:Hout|talk]]) 14:48, 8 June 2020 (UTC)
