I think the solution is not unique.

Asif Newaz on 4 Apr 2020

can u tell me where/which test suite u're facing problem?
cz I think the solution should be unique since there is only one parameter.

Binbin Qi on 5 Apr 2020

In the test2. Why [7 3 4 5 6] is not right?

Asif Newaz on 5 Apr 2020

ok..i see..
if there are more than one possibilities..they should be placed in sorted manner. that should do it

Binbin Qi on 5 Apr 2020

sorted?[3 4] or [4 3] in test2?

Asif Newaz on 6 Apr 2020

sorted based on the marks --
[40,50] == [4,3]

found it difficult but fun :)

Rafael S.T. Vieira on 14 Oct 2020

The problem is not difficult, but the test suite should accept all possible solutions since there is not an unique order, for instance at test cases #2 and #4. Sorting values increases this problem's difficulty since there may be several works with the same (or complementary) weight that can be done to achieve the same score (a proper description should be added to the problem since there may cases which are not trivial to sort).

PS: In this problem when any two works have the same deadline, but their marks differ, the lowest mark should come first (which seems weird). And no explanation is given for two works that have the same deadline and mark (but at least there isn't a case at the test suite).
