Write a function that verifies whether a Racket value is a Braun tree. Note that the number of nodes in a Braun tree uniquely determines its shape.

The goal is to ensure that the efficiency of your solution is roughly proportional to the size of the tree, and not larger than this. To reach this goal, you must ensure that you do at most one recursive application on each subtree. Furthermore, you are going to need more information from the recursive application than simply whether or not the subtree is a valid Braun tree. To this end, the specification of the main function you will write is a little unusual.

Write the function brt-verify, which consumes a Racket value t and produces false if t is not a valid Braun tree. If t is a valid Braun tree, brt-verify will produce some useful non-Boolean value. You get to choose this value in order to facilitate your implementation. Choosing wisely will make your job easier. Spend some time thinking before you start coding.

Given an implementation of brt-verify meeting this specification, it is easy to write a verification predicate
