   Maximum Product Subsequence of Exactly K Elements Using Dynamic Programming

   Find the maximum product that can be obtained by selecting exactly k elements from an integer array. The solution uses dynamic programming by maintaining both the maximum and minimum products for each subsequence size. Keeping both values is important because multiplying two negative numbers can produce a positive maximum product. The approach correctly handles positive numbers, negative numbers, zero, odd and even values of k, and all-negative arrays.
