Thanks siebenschlaefer!
only after your explanation I understood what task wants from me!

Thanks for the explanation, siebenschlaefer. It was fairly straightforward once I understood what was needed.

You have a sequence of values, e.g. [value1, value2, value3, value4, value5, value6, value7, value8, value9] and a function (predicate) that takes one argument and returns true or false. If you'd call the function for each argument you might get something like [true, true, true, false, true, true, false, false, true]. If you remove all values from the sequence up until (but not including) the first one that evaluates to false, you get this: [value4, value5, value6, value7, value8, value9] (because predicate(value1), predicate(value2), and predicate(value3) are true).

Your task: Write a function that takes a sequence and a predicate and returns a new sequence starting from the first element for which predicate(element) returns false.

Me too, I am slow at programming, I even unlocked the solution and did not really understand!

Guys ... I don't understand this one. What does this mean, "You want to remove the longest prefix of elements such that the predicate is true for each element."

You multiplied the number, nice!

now see if you can manipulate the array sans loops :)

My apologies. This is my first time posting a comment.

Please mark your comment as spoiler if it contains solution relevant information.

interesting code!

Great kata to practice using the range function!
