( 1611 ) E Jeff and Permutation PROGRAMMING greedy 2200

B"Jeff's friends know full well that the boy likes to get sequences and arrays for his birthday. Thus, Jeff got sequence p1, xe2 x80 x89p2, xe2 x80 x89..., xe2 x80 x89pn for his birthday. Jeff hates inversions in sequences. An inversion in sequence a1, xe2 x80 x89a2, xe2 x80 x89..., xe2 x80 x89an is a pair of indexes i, xe2 x80 x89j (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89i xe2 x80 x89< xe2 x80 x89j xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n), such that an inequality ai xe2 x80 x89> xe2 x80 x89aj holds. Jeff can multiply some numbers of the sequence p by -1. At that, he wants the number of inversions in the sequence to be minimum. Help Jeff and find the minimum number of inversions he manages to get. The first line contains integer n (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x892000). The next line contains n integers -- sequence p1, p2, ..., pn (|pi| xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89105). The numbers are separated by spaces. In a single line print the answer to the problem -- the minimum number of inversions Jeff can get."...
