(5 +2 points) You are given an array A[1..n] of positive numbers where Ai] is the stock price on day i. You are allowed to buy the stock once and sell it at some point later. For each day you own the stock you pay S1 fee. Design a divide-and-conquer algorithm that will return a pair (i,j) such that buying the stock on day i and selling it on day j will maximize your gain The complexity of the algorithm...
8. (1) Implement the minimum subsequence sum using divide-and-conquer. (30 points) (2) For the array =[4-3 5-2-1 2 6-2, you should provide the solution using the minimum subsequence sum like the example in class. Test the sample for your code. (3) Obtain the T(n) expression for the above algorithm
Consider the problem where you are given an array of n digits
[di] and a positive integer
b, and you need to compute the value of the number in that
base.
In general, you need to compute
For example:
(1011)2 = 1(1) + 1(2) + 0(4) + 1(8) = 11;
(1021)3 = 1(1) + 2(3) + 0(9) + 1(27) = 34, and
(1023)4 = 3(1) + 2(4) + 0(16) + 1(64) = 75.
In these examples, I give the digits...
The zigzag sorting problem takes an array data of size n and outputs a per- mutation where data[1] <data[2] > data[3] = data[4] > data[5] S..., all the way to the end of the array. (In general data[i] = data[i+1] if i is odd and data[i] > data[i+1] if i is even.) Answer the following questions about developing algorithms for the zigzag sorting problem. 1. Give pseudocode for a brute force algorithm for zigzag sorting. Your pseudocode just needs to...
(20 points) You are given an array A of distinct integers of size n. The sequence A[1], A[2], ..., A[n] is unimodal if for some index k between 1 and n the values increase up to position k and then decrease the reminder of the way until position n. (example 1, 4, 5, 7, 9, 10, 13, 14, 8, 6, 4, 3, 2 where the values increase until 14 and then decrease until 1). (a) Propose a recursive algorithm to...
Create and implement a C++ class, RandomGenerator, that: Allocates and stores an array of random floating point numbers between 0 and 1. The size of the array is passed into the constructor. The class contains a next() function which returns a new random number from the array every time the next() function is called (without calling rand()). Deletes any memory allocated on the heap when the class is destroyed. Note: This trick pre-calculates random numbers and saves execution time by...
You will be given an array of N elements sorted small to large. For the X and Y values that satisfy the X ≤ Y condition, draw the flow diagram of the algorithm that finds the start and end addresses of the region with the numbers greater than X and less than Y with the divide and manage approach and with O (logN) complexity. Also code the algorithm in c language. (not c++) Example: A[0…8] array 3, 5, 7, 9,...
C++ please, thank you! Design a class named ArrayClass that has an array of floating-point numbers. The constructor should accept an integer argument and allocate the array on the heap to hold that many numbers. The default constructor should allocate an array that can hold one number. When the user attempts to store items, you must make a copy constructor that correctly produces a new copy of an ArrayClass object from an old one. If the user attempts to store...
solution is required in pseudo code please.
2 Knapsack Problem În al Knapsack problem. given n items(11-12. . . . . 1"} with weight {w1·W2. . . . . ux) and value (n 2, .., nJ, the goal is to select a combination of items such that the total value V is maximized and the total weight is less or equal to a given capacity In this question, we will consider two different ways to represent a solution to the...
Suppose we are given two sorted arrays (nondecreasing from index 1 to index n) X[1] · · · X[n] and Y [1] · · · Y [n] of integers. For simplicity, assume that n is a power of 2. Problem is to design an algorithm that determines if there is a number p in X and a number q in Y such that p + q is zero. If such numbers exist, the algorithm returns true; otherwise, it returns false....
