WebHere’s how you create a new leaf: Node makeLeaf(Node p) { Node leaf = new Node(); leaf.parent = p; leaf.depth = p.depth + 1; if (p.depth - p.jump.depth == p.jump.depth - p.jump.jump.depth) { leaf.jump = p.jump.jump; } else { leaf.jump = p; } return leaf; } Parent and depth assignments are hopefully obvious. But what is this?
