Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Won't use sprintf or stringstream? Also, how is this clever?
How does this finish in time
because you cannot have conflicting types for a function in C, unless you use a very specific feature, which this kata aims to make you discover ;-)
why is it erroring when trying to overload like:
static char* add
static int add
It is just too slow to run in time. try to optimize.
maybe a test error?
