Given a binary tree, return the values of its boundary in anti-clockwise direction starting from root. Boundary includes left boundary, leaves, and right boundary in order without duplicate nodes. Left boundary is defined as the path from root to the left-most node. Right boundary is defined ...
The boundary of a binary tree is the concatenation of the root, the left boundary, the leaves ordered from left-to-right, and the reverse order of the right boundary. The left boundary is the set of nodes defined by the following: The root node's left child is in the left boundary. ...

1对boundary理解有误,比如左边的boundary,要是子树中没有左子树,右子树的点也是bounday的;同理右boundary也一样 2 root直接单独处理会简单些

Problem statement: Given a binary tree, print the boundary sum of the tree.SolutionFirst of all we need to understand what the boundary sum of a binary tree is? It's simply the cumulative sum of all boundary nodes surrounding the tree. For the following example:The...

Given a binary tree, perform the boundary traversal of it. The solution should print the boundary nodes starting from the root of the tree, in an anti-clockwise direction, without any duplicates.
