Answer #1

Quick Select Algorithm is an version of Quick-Sort Algorithm. We use QuickSort to sort the list but Quick-Select is used to get the kth smallest element in list.

In this algorithm, after finding the pivot, Instead of partition both the sides again and again we partition only the side which will give us the element.

  • If index of pivot is less than k, we partition right part
  • If index of pivot is equal to k, we return element
  • If index of pivot is greater than k, we partition left part

Give pseudocode for a memoized algorithm that computes n factorial. You will want to think about the implementation of an appropriate data structure as well as a sentinel value for this problem. Note: a memoized factorial algorithm is not considered dynamic programming, as factorial does not encounter repeated subproblems while recursing. However, memoizing this algorithm is the same process as memoizing a dynamic programming algorithm.

Acme Super Store is having a contest to give away shopping sprees to lucky families. If a family wins a shopping spree each person in the family can take any items in the store that he or she can carry out, however each person can only take one of each type of item. For example, one family member can take one television, one watch and one toaster, while another family member can take one television, one camera and one pair...
