Create a C++ Header Function with DYNAMIC programing with the following details: longest common subsequence input: a string a of length m and a string b of length n output: the longest string ssuch that s is a subsequence of both a and b; in the case of ties, use the substring that comes first alphabetically The dynamic programming algorithm for subsequences is similar to the one for substrings. Both involve a 2D array of strings, base cases, and a...

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...

2. (25) [Rising trend] Textbook Exercise 17 in Chapter 6. The problem to solve is, in other words, to select from a sequence of n numbers a subset, including the first number, such that the selected numbers make a longest monotonously increasing sequence. In the exercise b, (i) write an optimal substructure (with an explanation),ii) write the iterative dynamic programming algorithm (pseudocode), and (iii) show the running-time analysis. Hints: the algorithm in the exercise a is a greedy algorithm; the...

An array A of n integers is called semi-sorted if it is increasing until some index and then decreasing afterwards. In other words, there is some index 1 ≤ p ≤ n such that: • A[i] < A[i + 1] for 1 ≤ i < p, and • A[i] > A[i + 1] for p ≤ i < n. Note that in this case, A[p] is the maximum element of A. Give an algorithm with running time O(logn) that finds...

Convert the pseudocode into a C++ function
Decrease-by-Half Algorithm We can solve the same problem using a decrease-by-half algorithm. This algorithm is based on the following ideas: In the base case, n 1 and the only possible solution is b 0, e 1 In the general case, divide V into a left and rnight half; then the maximum subarray can be in one of three places: o entirely in the left half; o entirely in the right half; or o...

Problem Definition: Problem: Given an array of integers find all pairs of integers, a and b, where a – b is equal to a given number. For example, consider the following array and suppose we want to find all pairs of integers a and b where a – b = 3 A = [10, 4, 6, 16, 1, 6, 12, 13] Then your method should return the following pairs: 4, 1 15, 12 13, 10 A poor solution: There are...

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...

This C++ Program consists of: operator overloading, as well as experience with managing dynamic memory allocation inside a class. Task One common limitation of programming languages is that the built-in types are limited to smaller finite ranges of storage. For instance, the built-in int type in C++ is 4 bytes in most systems today, allowing for about 4 billion different numbers. The regular int splits this range between positive and negative numbers, but even an unsigned int (assuming 4 bytes)...
