It sets stack size. If you don't write it, your solution may crash with stack overflow (in deep recursive functions, for example).

    The only thing to add is that it's MS Visual C++-specific and won't work with GCC. In GCC you should specify -Wl,--stack=256000000 command line option to set stack size (in bytes).

        2MB. You can see this in the headers of .exe produced by MinGW.

      $ g++ -Wl,--stack=256000000 test.cpp
/usr/bin/ld: unrecognized option '--stack=256000000'
/usr/bin/ld: use the --help option for usage information

      Parameter --stack can be used only with MinGW. ;)

          Nohow. Stack size is a user limit under GNU/Linux and doesn't depend on compiler. You can use ulimit -s to change/view it.

“#pragma comment(linker, ”/STACK:36777216“)” Is it usable only in the on-line judge or anywhere you want?

    It's usable anywhere with Microsoft Visual C++ — on your local machine and so on.
