I am struggling with this problem
Design of algorithms - divide-and-conquer: (a) Design a divide-and-conquer algorithm DC_PROD that receives as input an array A with n>0 integers and returns the product of the elements in A. You may assume n is a power of 2. In your algorithm identify the relevant parts of a divide-and-conquer strategy: (i) divide, (ii) conquer, and (iii) combine. (b) Establish the recurrence relation for the running time, T(n), of DC_PROD. (c) Apply the Master Theorem to give a tight bound for T(n).
Question 8 Choose one of the following answer correctly
Suppose we wish to sort the following values: 84, 22, 19, 11, 60, 68, 31, 29, 58, 23, 45, 93, 48, 31, 7. Assume that: we have three pages of memory for sorting; we will use an external sorting algorithm with a 2-way merge; a page only holds two values. We do not use double buffering and we use quick sort in pass 0 to produce the initial runs. For each sorting pass, show the contents of all temporary files except that you should fully utilize the buffers by sorting every 3 pages into a run in pass 0. Could you show step by step detailed explaination for this?
