If the input string s is a word like 'hello', then the output word product p is a number based on the correspondence a=1, b=2, ... z=26. Assume the input will be a single word, although it may mixed case. Note that A=a=1 and B=b=2.
s = 'hello'
p = 8 * 5 * 12 * 12 * 15 = 86400
Bonus question: How close can you get to a word product of one million?
