Arthur and Questions

After bracket sequences Arthur took up number theory. He has got a new favorite sequence of length n (a₁, a₂, ..., a_n), consisting of integers and integer k, not exceeding n.

This sequence had the following property: if you write out the sums of all its segments consisting of k consecutive elements (a₁  +  a₂ ...  +  a_k,  a₂  +  a₃  +  ...  +  a_k + 1,  ...,  a_{n - k + 1}  +  a_{n - k + 2}  +  ...  +  a_n), then those numbers will form strictly increasing sequence.

For example, for the following sample: n = 5,  k = 3,  a = (1,  2,  4,  5,  6) the sequence of numbers will look as follows: (1  +  2  +  4,  2  +  4  +  5,  4  +  5  +  6) = (7,  11,  15), that means that sequence a meets the described property.

Obviously the sequence of sums will have n - k + 1 elements.

Somebody (we won't say who) replaced some numbers in Arthur's sequence by question marks (if this number is replaced, it is replaced by exactly one question mark). We need to restore the sequence so that it meets the required property and also minimize the sum |a_i|, where |a_i| is the absolute value of a_i.
