Operator list

Write a function $operate(data, ops)$ that applies in turn the operators listed in $ops$ to the $data$ . The data is a list of $n>0$ integers. Then $ops$ is a string of length $n-1$ made up of the characters ’+’ and ’*’ standing respectively for sum and product. The result of the function is to be the outcome of the operations in left-to-right order both of $ops$ and of $data$ : the first operator is applied to the first two integers, the second operator is applied to the outcome and the third integer, and so on.
