Suppose that you are given Binary Search Tree T and and integer k. Assume that nodes of T hold distinct integers. Give two integers a and b (ab) in T let Distancea,b la +b-k Using pseudo code, write an algorithm that gets T and k as inputs and finds a pair a, bE T such that Distancca,b min{Distanceu,v |u ET,vET, u f v}. Analyze the worst-case time complexity of your algorithm and justify the correctness
