The compositor arranges the pages of a book from/kloc-0 to 50 pages. If each number in the page number of a book uses a different block, ask him how many blocks he needs for a * * *? Answer and analysis:
Segmented calculation:
From 1 to 9 pages, * * 9 pages, each page uses a block of * * type 1×9=9 (block);
From 10 to 19 pages, * * 10 pages, each page uses two types of blocks * * 2× 10 = 20 (blocks);
From 20 pages to 29 pages, * * 10 page, each page uses two blocks of * * 2× 10=20 (block) type;
From 30 pages to 39 pages, * * 10 pages, each page uses two blocks of * * 2× 10=20 (block) type;
From 40 pages to 49 pages, * * 10 pages, each page uses two blocks of * * 2× 10=20 (block) type;
On page 50, *** 1 (but with two digits) uses two types of blocks.
So: 50 pages of books * * * use 9+20+20+2 = 91(block) (type).
