LeetCode: Symmetric Tree [101]
【题目】 Given a binary tree, check whether it is a mirror of itself (ie, symmetric around its center). For example, this binary tree is symmetric: 1 / 2 2 / \ / 3 4 4 3 But the following is not: 1 / 2 2 \ 3 3 No...

LeetCode: Recover Binary Search Tree [099]
【题目】 Two elements of a binary search tree (BST) are swapped by mistake. Recover the tree without changing its structure. Note: A solution using O(n) space is pretty straight forward. Could you devise a constant space solution? confused what "{1,#,2,3}" ...

LeetCode: Validate Binary Search Tree [098]
【题目】 Given a binary tree, determine if it is a valid binary search tree (BST). Assume a BST is defined as follows: The left subtree of a node contains only nodes with keys less than the node's key. The right subtree of a node contains only nodes with ke...

HDU 4836 The Query on the Tree lca || 欧拉序列 || 动态树
lca的做法还是很明显的,简单粗暴, 不过不是正解,如果树是长链就会跪,直接变成O(n)、、 最后跑的也挺快,出题人还是挺阳光的。。 #include #include #include #include #include #include #include #include #include #include #include #include #inclu...
