Given a binary tree, you need to check whether sum of all covered elements is equal to sum of all uncovered elements or not. In a binary tree, a node is called Uncovered if it appears either on left boundary or right boundary. Rest of the nodes are called covered. For example, conside...
Given the root of a binary tree, return the number of nodes where the value of the node is equal to the sum of the values of its descendants. A descendant of a node x is any node that is on the path from node x to some leaf node. The sum is considered to be 0 if the node ...
