Quite recently a creative student Lesha had a lecture on trees. After the lecture Lesha was inspired and came up with the tree of his own which he called a k-tree. A k-tree is an infinite rooted tree where: each vertex has exactly k children; each edge has some weight; if we look at the edges that goes from some ...
