As discussed in the previous post, Splay tree is a self-balancing data structure where the last accessed key is always at root. The insert operation is similar to Binary Search Tree insert with additional steps to make sure that the newly inserted key becomes the new root.

Webinsert 7 at root Figure 1: Splay tree insertion. (b)To perform delete(15), we first search for 15 in the tree. We first perform a zig-zig rotation, followed by a zig-zag, followed by a zig to bring 15 to the root (see Fig.2). Next, we perform splay(15) on the root’s right subtree, but since we fall out of the tree at node 17 itself, so huda alsalem + reserch gate
