under the examples it clearly states that the years are classified in centuries using 'STRICT' construction instead of popular.
This means 1-100 is 1st century, 2000 is 20th century as it shows in the examples given.

Неприятная ката от слова совсем. Алгоритм был написан правильный, но тесты не проходило. В решении все тоже самое, только вместо вектора используемся дек.

You can't change the order. (a+c)*b is invalid.

i got the max and it says no it want onather thing

The test you are failing is not [1, 5, 6] but [5, 6, 1] Max you can get is 5 * (6 + 1).

Remember that you have to use numbers in their original order, you cannot reorder them.

Your solution is buggy, it is not a kata issue.

In what language?

You cannot swap the operands. For example, with the given numbers, you cannot get the expression (1 + 3) * 2 = 8.

I think the expression: (a + c) * b, was not taken into consideration while designing this Kata. Removing it from your array of possible expressions should fix it if you're using the same approach as mine.

All this type kata should solve after creating own prime number generator

if you want something to be fixed then demonstrate how it is broken such that another person can reproduce the situation. otherwise nobody has any clue what you're referring to (and most people will probably assume there's nothing wrong and that you're simply dealing with a bug in your own code)

Please fix the test!

IMHO current constraints makes it 6kyu.
At 7kyu brute-force solutions should be accepted.
