Statement

Young designer Vasya creates logo for his company. He imagines it to be a company name, each letter colored either blue or orange.

Vasya wants to color letters so that the name consisted of single-color substrings of equal length. Color of sequential substrings must alternate. In other words if first X letters are colored orange, next X must be colored blue etc.

For each letter of the alphabet, Vasya decided if it is allowed to be colored blue, orange, either of those colors, or not allowed to be used at all. Vasya wants to color company name in two colors so that his requirements for splitting into substrings and constraints on letter colors are satisfied.

Your program must calculate number of different ways Vasya may color his company name.
