If the worm starts from the first sheet of the first volume and finishes at the last one of the second volume, how could the answer for the sample input be 2, given that the thikness of the book (not including the cover) is 10?

Worm can move both left and right. Stop for a while and think about it.

In some languages, the "first page" of a book is on the left side of the book when the book is placed on a shelf. In which case "10 1 1 2" == 22.

Just take two books and try - you will find answer immediately
