Implement an iterator over a binary search tree (BST). Your iterator will be initialized with the root node of a BST.
Calling next() will return the next smallest number in the BST.
Note: next()...

1. treap
众所周知, treap = tree + heap
也就是 treap 是具有堆性质的平衡二叉树(BST), 而堆性质的维护就靠一个随机值和旋转操作. 可以是小根堆也可以是大根堆.
在代码实现上, 左旋和右旋有太多的相似处, 可以用一个带旋转方向参数的 rotate 操作来完成.
模板...
