According to recent surveys run by various Computer Science Clubs at Canadian high schools, is a cool digit. That's why we are going to define the "coolness" of a number to be the number of s it has (e.g. has a coolness of , whereas has no coolness). This makes counting a very cool activity, which begs the question: exactly how cool is it to be able to count up to ? We are interested in finding the total coolness of all numbers from up to a given number.
There will be five lines of input, each containing a single number .
You should output five lines, each line the sum of the coolness of all the numbers from to inclusive.
