2. Otherwise, search recursively by comparing K with the element located at [n/4]. If it equal, then youre done. If its smaller then continue with the sublist to the left of n/4 3. If, on the other hand, its bigger than n/4|, then compare it with the element located [3n/4] and do exactly as you did in (2) i.e. you either found it at 3n/4] or you contir with one of the sublists that are on the left or right of [3n/4]. (a) Write the pseudocode of the above describe search algorithm. (b) Set up a recurrence desginating a lower bound on the number of key comparisons. (c) Set up a recurrence designating an upper bound on the number of key comparisions.
