Sum of Products

You are given an array, the net value is obtained by doing the following operations: 1) write down all pairs odd numbers from this array. 2) compute the product of each pair. 3) find the sum of all the products. For example, for a given array, for a given array [7,2,-1,2] Pairs (7, 2), (7, -1), (7, 2), (2, -1), (2, 2), (-1, 2) Products of the pairs 14, -7, 14, -2, 4, -2 Sum of the products 14 +
