Consider the Catalan numbers P(n) described here (it is also
described on page 372 of the book).
- Show a recursion-dependence tree for P(5) according to the recurrence relation.
- Design a bottom-up dynamic programming algorithm to compute P(n) based on the recurrence relation (without using the formula P(n) = (2n−2)!/(n!(n−1)!)). Analyze its asymptotic runtime efficiency.
- Design a top-down memoized algorithm to compute P(n) based on the recurrence relation (without using the formula P(n) = (2n−2)!/(n!(n−1)!)). Analyze its asymptotic runtime efficiency.

2. (40 pts) Let A, B, and C be three strings each n characters long. We want to compute the longest subsequence that is common to all three strings. (a) Let us first consider the following greedy algorithm for this problem. Find the longest common subsequence between any pair of strings, namely, LCS(A, B) LCS(B, C), LCS(A, C). Then, find the longest common subsequence between this LCS and the 3rd string. That is, supposing that the longest common pair wise...

Haloo , i have java program , Java Program , dynamic program Given a knapsack with capacity B∈N and -n- objects with profits p0, ..., p n-1 and weights w0, ..., wn-1. It is also necessary to find a subset I ⊆ {0, ..., n-1} such that the profit of the selected objects is maximized without exceeding the capacity. However, we have another limitation: the number of objects must not exceed a given k ∈ N Example: For the items...

problem 2
can use Det-Selection(A, p, q, r) as a sub-routine (i.e, you don't need to write its pseudo-code). To sort an array A, you will then call Det-QuickSort(A, 1, n). You also need to provide the worst case time complexity analysis of your algorithm. 2. (20 points) Given a set of n distinct numbers, we wish to find the k largest in sorted order using a comparison-based algorithm. Give an algorithm that implements each of the following methods, and...

What is the role of polymorphism? Question options: Polymorphism allows a programmer to manipulate objects that share a set of tasks, even though the tasks are executed in different ways. Polymorphism allows a programmer to use a subclass object in place of a superclass object. Polymorphism allows a subclass to override a superclass method by providing a completely new implementation. Polymorphism allows a subclass to extend a superclass method by performing the superclass task plus some additional work. Assume that...
