Key Salesforce Teams Description In a Salesforce organizational hierarchy, the structure is represented as a tree with n nodes, each corresponding to a team. A team is called a "key team" if it is an endpoint of any of the longest communication paths (diameters) within the hierarchy. For all the teams in the hierarchy, determine if they are key teams or not. Thus, return a binary array, where the i th value of the array will be 1, if the i th node is a key team. Else, the i th value of the array will be 0. Note: The diameter of a tree is defined as the number of edges in the longest path of the given tree. Example Consider the tree given below: 2 / \ 1 3 We can see that this tree has only one diameter, which is the unique path between nodes 1 and 3. The length of the diameter is 2. The end-points of the diameter are 1 and 3. Hence, nodes 1 and 3 are considered special, while node 2 is not considered a special node of the tree.
