+
+# reduce take the function given and take item from the
+# iterable and pass to function given to it. The first
+# parameter is the value initialized as the 3rd argument
+# to the reduce function. It do the processing and returns
+# a value which is used as next initialiizing value for the
+# first argument of the function provided in the reduce function
+# and so on for all items in iterable.
