Multiply a Row

Write a function $prod\_row(i, m)$ that receives the index $i$ of one row of a matrix of int’s $m$ and returns the product of all the integers in that row. The matrix of int’s is represented as a tuple of rows, each row being, in turn, a tuple of int’s. If $m$ has $n$ rows, we are guaranteed that $0 \leq i < n$ .

Observation

Observe that $0 \leq i < n$ implies that the tuple $m$ is nonempty, but nothing else.
