title: How to use functional programming to iterate and find maximum product of five consecutive numbers in a list?
body: <p>I have to use functional programming to implement the following function takes in a list of numbers from 0 to 9. The goal is to find the five consecutive elements of the list that have the greatest product. The function should return tuple of the index of the greatest product and the value of the greatest product <strong>without</strong> using the <em>max</em> function.</p>
  
  <p>I can easily implement this without functional programming but I am having trouble implementing it without any loops.
  This is my approach so far but the part that I am stuck on is how to loop through the array to find those consecutive five numbers without loops. I am trying to use map to do that but I don't think it is correct. Is it possible to incorporate enumerate in any way? Any help is appreciated. </p>
  
  <pre><code>def find_products(L):
      val = map(lambda a: reduce(lambda x,y: x*y, L),L)
      print (val)
  </code></pre>
