It's just a collection of solutions to coding problems on some well-known online judge platforms or contests. Use Makefiles to automate compilation, see Makefile and branch.mk for more information.

The solutions are based on a library inspired by C interfaces and implementations, and wrote in literate program form.

Maintainance of infrastructure and solving of problems are separated to different branches, to clone the infrastructure separately is possible, check out branch infra if you want.

I hope that the code could explain itself, but it failed to do that, apparently. Two kinds of Makefile are used, one in root directory (The Makefile in current directory), one in sub-directories(branch.mk).

If you are at root, the following targets are supported.

# create a new folder, then, 
# create a symbol link of branch.mk in that folder
$ make new 

# recreate symbol links in all branch directories, 
# which specified by PLATFORMS macro in Makefile
$ make refresh 

# delete all temporary files and symbol links
$ make clean

If you are at branch,

# create a new file, and edit it with editor, 
# which can be specified by ${EDITOR} in branch.mk,
# but to state it as an environment variable is recommended,
# some other programs(for example, visudo) also use $EDITOR.
$ make new

# create a new folder,
# the same as "make new" at root
$ make new-folder

# delete all temporary files
$ make clean
