( 10724 ) B Odd sum PROGRAMMING dp greedy implementation 1400

B"You are given sequence a1, xe2 x80 x89a2, xe2 x80 x89..., xe2 x80 x89an of integer numbers of length n. Your task is to find such subsequence that its sum is odd and maximum among all such subsequences. It's guaranteed that given sequence contains subsequence with odd sum. Subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. You should write a program which finds sum of the best subsequence. The first line contains integer number n (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89105). The second line contains n integer numbers a1, xe2 x80 x89a2, xe2 x80 x89..., xe2 x80 x89an ( xe2 x80 x89- xe2 x80 x89104 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89ai xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89104). The sequence contains at least one subsequence with odd sum. Print sum of resulting subseqeuence. In the first example sum of the second and the fourth elements is 3. "...
