Find parent of a node in binary tree python
WebYou are given a binary tree with an integer value (which might be positive or negative) at each node. Create an algorithm that count the number of pathways that add up to a specific value. The route does not have to begin or end at a root or a leaf, but it must descend (traveling only from parent nodes to child nodes) arrow_forward WebA tree node can be a “parent” and a “child” simultaneously, because they are not exclusive. For instance, a node ‘b’ can be the child of node ‘a’, while being the parent to nodes ‘d’ and ‘e’. However, a child can only have one parent, while a parent can have multiple children. Trees are composed of nodes
