Given a vector of integers named vec provided to you below, find the sum of the product of all pairs of vector elements. You should declare an integer variable named result and store the final product in this variable. For example, given the vector vec to be {1, 2, 3}, the possible pairs are (1,2), (1,3), and (2,3) . So the result would be (1 * 2) + (1 * 3) + (2 * 3), which is 11. Another example: Given the vector vec to be {2, 4, 6, 8}, the possible pairs are (2,4), (2,6), (2.8), (4,6), (4,8), and (6,8) . So the result would be (2 * 4) + (2 * 6) + (2 * 8) + (4 * 6) + (4 * 8) + (6 * 8) which is 140 . If the vector is empty or has only 1 element the result should be 0. Run your code against the three (3) vectors below. Make sure that you reset the result before processing each vector. vector vec1 {1,3,5,15,16,17,18,19,20}; vector vec2 {5}; vector vec3 {}; Output: Display each vector to the terminal followed immediately by the corresponding result.
