c.To go up, down, or across (a slope) diagonally, as in skiing. 2.To cause to move laterally on a pivot; swivel:traverse an artillery piece. 3.To extend across; cross:a bridge that traverses a river. 4.To look over carefully; examine:"Someday I plan to read the classics. Some...
A binary tree isthreadedby making all right child pointers that would normally be null point to the inorder successor of the node (ifit exists), and all left child pointers that would normally be null point to the inorder predecessor of the node. 就是说线索二叉树实际上是把所有原本为空的...
The entire solution can be found here - http://ideone.com/zFMGKU The solution returns a vector of vectors with each inner vector containing the elements in the tree in the correct order. you can try solving it here - https://oj.leetcode.com/problems/binary-tree-level-order-traversal/...
