Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add git@github.com:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.

int rulled_out[10000 / sizeof(int) + 1];
int num_left;

// Try guess GUESS and mark the entries in RULLED_OUT that match the
// numbers that cannot be the secret (i.e. numbers that compared to
// GUESS are not COMP).
void update_rulled_out(int guess, int comp);
