Given a matrix A and scalars r,c,i, find the product of two elements, with the first element located at row r and column c (double indexing scheme) and the second element located at i (single indexing scheme).

For example, let A = [ ] and r = 2, c = 3, i = 8. Then the first element is 7 and the second element is 6, making their product 42.
