In mathematics, a metric space is a set for which distances between all members of the set are defined. Those distances, taken together, are called a metric on the set. A metric on a space induces topological properties like open and closed sets, which lead to the study of more abstract topological spaces.
The most familiar metric space is 3-dimensional Euclidean space. In fact, a "metric" is the generalization of the Euclidean metric arising from the four long-known properties of the Euclidean distance. The Euclidean metric defines the distance between two points as the length of the straight...

VSL, 21 bytes
puts(`Hello, World!`)
Okay after over one year development, the day has come where I can post this :D
VSL does not have a fancy print function at the moment so this uses the POSIX puts function. Additionally because puts is a C-function, we must use a byte sequence rather than a...
I am working on a quad tree level two and I am wondering how to recursively free children nodes and then freeing the parent nodes.
void freeTree(Node *node){
int i;
if (node->child[0] == NULL){
free(node);
}
else {
for(i=0 ; i<4; i++){
freeTree(node->child[I];
}
}
