Chinese Multiplication Table - 50 entries

Print a Chinese multiplication table in Vim. In China, every kid is asked to memorize this table. And thanks to the mono-syllabism of Chinese characters, it is not that hard. Printing the multiplication table is also a good exercise for programming beginners. For-loop, escaped characters, etc... There should be some special ways to print it in Vim.

Draw the Go board - 110 entries

which is a 19×19 lines board. Here we use ascii characters only for simplicity. See diff file to get a sense. (See also http://en.wikipedia.org/wiki/Go_(game))

Change The Perspective - 36 entries

This is a go game recodes file(.sgf file, refer to http://www.red-bean.com/sgf/). It base on such a coordinate system: in vertical direction, is from top(farthest end) to bottom, mark as a,b,c,...,s(19*19 board); in horizontal direction, is from left to right, uses the same notations. For Example, the coordinate notation 'cq', is the position at the bottom-left corner(vertical coordinate first). The record is from one player's perspective. We need to change to another's, but we don't want to change coordinate system, let it keep top to bottom and left to right. so we have to change the coordinates, a <-> s, b <-> r,c <-> q, etc. the Position 'cq', as transformation, it will be 'qd'.
