... • In this form, every operator appears before its operand(s). An inorder traversal of an expression tree yields the infix form of the expression. • In this form, every operator appears between its operand(s). A postorder traversal of an expression tree yields the postfix (or reverse polish) form of ...

Splay Trees
... Search down from the root, looking for i. If search reaches a node x containing i, we splay at x and return the pointer to x. If search reaches a null node, we splay the last non-null node, and return a null pointer. ...
