Given n distinct items:
- Assuming n is a power of 2, write down a recursive divide-and-conquer algorithm for solving simultaneous minimum and maximum, using n = 2 as the bottom of the recursion.
- If we let T(n) denote the number of comparisons done by your algorithm, write down the recurrence relation satisfied by T(n).
- Solve exactly (without using the “big O” notation) the recurrence relation for T(n), showing all the details of your work.

Suppose the following is a divide-and-conquer algorithm for some problem. "Make the input of size n into 3 subproblems of sizes n/2 , n/4 , n/8 , respectively with O(n) time; Recursively call on these subproblems; and then combine the results in O(n) time. The recursive call returns when the problems become of size 1 and the time in this case is constant." (a) Let T(n) denote the worst-case running time of this approach on the problem of size n....

In the text box below, write down a divide and conquer algorithm for counting the number of entries in a sorted array of ints that are smaller than a given value. In other words, the function takes as input an array A and an int value and returns the number of ints in A that are less than value. To get any credit, your solution must use the divide and conquer technique. To get full credit, your solution should run in time in the...
