Given a binary tree, return thelevel ordertraversal of its nodes' values. (ie, from left to right, level by level). For example: Given binary tree{3,9,20,#,#,15,7}, 3 / \ 9 20 / \ 15 7 return its level order traversal as: [ [3], [9,20], [15,7] ] ++++++++++++...

For each test case, first printf in a line "Yes" if the tree is unique, or "No" if not. Then print in the next line the inorder traversal sequence of the corresponding binary tree. If the solution is not unique, any answer would do. It is guaranteed that at least one solution exi...
An inorder binary tree traversal can be implemented in a non-recursive way with a stack. For example, suppose that when a 6-node binary tree (with the keys numbered from 1 to 6) is traversed, the stack operations are: push(1); push(2); push(3); pop(); pop(); push(4); pop(...
表达式树的叶子节点是操作数(operand),如常数或者变量,而其他的节点为操作符(operator...的方法称为中序遍历(inordertraversal)。由于其产生的表达式类型,这种遍历很容易记忆。后序遍历另一种方法,先遍历打印左子树,然后遍历打印右子树,最后打印根节点,得到的表达式为...
