+Write a function called arrow defined as follows:
+
+def arrow(my_char, max_length):
+The function accepts two parameters: the first is a single character, the second is a maximum size.
+The function returns a string representing an "arrow" structure (see example), built from the input, where the center of the arrow (the longest line) is the length of the size passed as a parameter.
+
+An example of running the arrow function
+print(arrow('*', 5))
