我们需要支持两种旋转操作,右旋操作和左旋操作。 如下图,我们将节点 B 旋转到 A 处。 旋转操作主要是用于维护 Treap 的堆性质,由上图可以看出旋转过程会改变上下两个节点的父子关系,类似于堆插入操作的上浮,事实上,左旋操作就是将左儿子转到该节点,右旋操作就是将右儿子转到该节点。

Build 实际上我们可以很容易地根据权值\(O(n)\)建树(类似于笛卡尔树),不过这似乎并没有什么用,直接暴力Insert就完事了。 Tips: \(1.\)为了防止找前驱后继时要找的数比Splay中的数都小/大(比如我们要找Splay最小的数的前驱),我们可以一开始就加入\(-\infty,\infty\)两个哨兵节点。
