Question
Chapter 4, Problem 2.1E
Program Plan Intro
File compression:
- It is the process of shrinking a file in order to reduce the actual size of the file. This is done in order to free up spaces on the storage media.
- It is also easy for the user to attach the compressed file to e-mail which also reduces the time required for the file transmission.
- Compressed files are also called as zipped files.
- If a person gets a compressed file, then he/ she should unzip the file in order to get the original form.

Design a dynamic programming algorithm for the problem described below
Input: A list of numbers A = = [a1,..., an].
Output: A contiguous subsequence of numbers with the maximum sum.
The algorithm must take O(n) time. You must also write and explain the recurrence.
(I am looking for an i ≥ 1 and k ≥ 0 such that a + ai+1 + ···ai+k has the largest possible sum among all
possible values for i and k.)
Example 1:
Input: A[5, 15, -30, 10, -5, 40, 10].
Output: [10, 5, 40, 10]
Example 2:
Input: A = [7, 5, 7, 4, -20, 6, 9, 3, -4, -8, 4]
Output: [6,9,3]
Design a dynamic programming algorithm for the Longest Increasing Subsequence problem
described below:
Input: A sequence of n integers
Output: The length of the longest increasing subsequence among these integers.
The algorithm must take O(n²) time. You must also write and explain the recurrence.
Example 1:
Input: [5, 3, 6, 8, 4, 6, 2, 7, 9, 5]
Output: 5 ([3, 4, 6, 7, 9])
Example 2:
Input: [12, 42, 66, 73, 234, 7, 543, 16]
Output: 6 ([42, 66, 73, 234, 543])
Design a dynamic programming algorithm for the Subset Sum problem described below:
Input: A set of n integers A and an integer s
Output: A subset of A whose numbers add up to s, or that no such set exists.
The algorithm must take O(n·s) time. You must also write and explain the recurrence.
Example 1:
Input: A = {4, 7, 5, 2, 3}, s = 12
Output: {7,2,3}
Example 2:
Input: A{4, 7, 5,3}, s = 6
Output: 'no such subset'

In other words, you will program the sine or cosine function yourself, without using any existing solution. You can enter the angles in degrees or radians. The program must work for any input, e.g. -4500° or +8649°. The function will have two arguments: float sinus(float radians, float epsilon); For your own implementation, use one of the following relations (you only need to program either sine or cosine, you don't need both): Tip 1: Of course, you cannot calculate the sum of an infinite series indefinitely. You can see (if not, look in the program) that the terms keep getting smaller, so there will definitely be a situation where adding another term will not change the result in any way (see problem 1.3 – machine epsilon). However, you can end the calculation even earlier – when the result changes by less than epsilon (a pre-specified, sufficiently small number, e.g.…arrow_forwardWrite a C program that counts the number of ones (set bits) in the binary representation of a given number.

To get full points, you must be able to explain to the instructor the individual parts of the IntelHex line (see below), as well as any part of your code. Definition:The checksum is calculated as the two's complement of the sum of the individual bytes from the beginning of the line to the checksum. Example:If you enter this string: :10010000214601360121470136007EFE09D21901XX You should get a checksum of 40 instead of XX. Demonstrate the completion of the task by calculating checksums, for example, for the following strings: :100010000C9445000C9445000C9445000C944500xx:100020000C9445000C9445000C9445000C944500xx:100030000C9445000C9445000C9445000C944500xx:100040000C9445000C9445000C9445000C944500xxarrow_forward
