I am just 2 days novice in LaTeX. Started yesterday and formatted a book in two days which looks nice now

I have wrote some text and it is generating fine pdf. The problem I am facing now is, I want to print pages in different order. For example, if I have 100 pages book, the I want to print pages in 100,1 then 99,2 then 98,3 and so on with odd numbered pages on right and even numbered pages on left. Is it possible?
