"Players The files SomePlayers.txt initially contains the names of 30 football play- ers. Write a program that deletes those players from the file whose names do not begin with a vowel."
Answers
Answer:
I am writing a Python program that deletes players from the file whose names whose names do not begin with a vowel which means their names begin with a consonant instead. Since the SomePlayers.txt is not provided so i am creating this file. You can simply use this program on your own file.
fileobj= open('SomePlayers.txt', 'r')
player_names=[name.rstrip() for name in fileobj]
fileobj.close()
vowels = ('a', 'e', 'i', 'o', 'u','A','E','I','O','U')
player_names=[name for name in player_names
if name[0] in vowels]
fileobj.close()
print(player_names)
Explanation:
I will explain the program line by line.
First SomePlayers.txt is opened in r mode which is read mode using open() method. fileobj is the name of the file object created to access or manipulate the SomePlayers.txt file. Next a for loop is used to move through each string in the text file and rstrip() method is used to remove white spaces from the text file and stores the names in player_names. Next the file is closed using close() method. Next vowels holds the list of characters which are vowels including both the upper and lower case vowels.
player_names=[name for name in player_names
if name[0] in vowels]
This is the main line of the code. The for loop traverses through every name string in the text file SomePlayers.txt which was first stored in player_names when rstrip() method was used. Now the IF condition checks the first character of each name string. [0] is the index position of the first character of each players name. So the if condition checks if the first character of the name is a vowel or not. in keyword is used here to check if the vowel is included in the first character of every name in the file. This will separate all the names that begins with a vowel and stores in the list player_names. At the end the print statement print(player_names) displays all the names included in the player_names which begin with a vowel hence removing all those names do not begin with a vowel.

Answer:
Lack of Strategy
Many of the most common MIS issues can be traced back to a lack of a solid strategy. Information systems leaders are well aware of the many tools available to gather data on their network. But putting that information to use is often a challenge.
At one time, technology departments served as a separate operation, providing tech support and keeping an organization’s server equipment running. Today, MIS leadership often sits alongside other business leaders, working together to ensure that the technology being used supports the overall mission of the company moving forward.
Meeting Organizational Needs
MIS plays an ever-increasing role in organizations, with professionals relying on technology for every aspect of operations. Sales and marketing rely heavily on customer relationship software to track client interactions, for instance, while accounting needs its own software for billing, invoicing and financial tracking.
With more than half of all companies now relying on big data analytics, MIS is playing an even more important role. Before making a decision, today’s management teams are likely to pull reports on existing activity to ensure they use facts rather than make educated guesses.

what is real time os ?
Answers
Explanation:
A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time applications that process data as it comes in, typically without buffer delays. Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter increments of time. A real-time system is a time-bound system which has well-defined, fixed time constraints. Processing must be done within the defined constraints or the system will fail. They are either event-driven or time-sharing. Event-driven systems switch between tasks based on their priorities, while time-sharing systems switch the task based on clock interrupts. Most RTOSs use a pre-emptive scheduling algorithm.

A Quicksort (or Partition Exchange Sort) divides the data into 2 partitions separated by a pivot. The first partition contains all the items which are smaller than the pivot. The remaining items are in the other partition. You will write four versions of Quicksort:
• Select the first item of the partition as the pivot. Treat partitions of size one and two as stopping cases.
• Same pivot selection. For a partition of size 100 or less, use an insertion sort to finish.
• Same pivot selection. For a partition of size 50 or less, use an insertion sort to finish.
• Select the median-of-three as the pivot. Treat partitions of size one and two as stopping cases.
As time permits consider examining additional, alternate methods of selecting the pivot for Quicksort.
Merge Sort is a useful sort to know if you are doing External Sorting. The need for this will increase as data sizes increase. The traditional Merge Sort requires double space. To eliminate this issue, you are to implement Natural Merge using a linked implementation. In your analysis be sure to compare to the effect of using a straight Merge Sort instead.
Create input files of four sizes: 50, 1000, 2000, 5000 and 10000 integers. For each size file make 3 versions. On the first use a randomly ordered data set. On the second use the integers in reverse order. On the third use the
integers in normal ascending order. (You may use a random number generator to create the randomly ordered file, but it is important to limit the duplicates to <1%. Alternatively, you may write a shuffle function to randomize one of your ordered files.) This means you have an input set of 15 files plus whatever you deem necessary and reasonable. Files are available in the Blackboard shell, if you want to copy them. Your data should be formatted so that each number is on a separate line with no leading blanks. There should be no blank lines in the file. Even though you are limiting the occurrence of duplicates, your sorts must be able to handle duplicate data.
Each sort must be run against all the input files. With five sorts and 15 input sets, you will have 75 required runs.
The size 50 files are for the purpose of showing the sorting is correct. Your code needs to print out the comparisons and exchanges (see below) and the sorted values. You must submit the input and output files for all orders of size 50, for all sorts. There should be 15 output files here.
The larger sizes of input are used to demonstrate the asymptotic cost. To demonstrate the asymptotic cost you will need to count comparisons and exchanges for each sort. For these files at the end of each run you need to print the number of comparisons and the number of exchanges but not the sorted data. It is to your advantage to add larger files or additional random files to the input - perhaps with 15-20% duplicates. You may find it interesting to time the runs, but this should be in addition to counting comparisons and exchanges.
Turn in an analysis comparing the two sorts and their performance. Be sure to comment on the relative numbers of exchanges and comparison in the various runs, the effect of the order of the data, the effect of different size files, the effect of different partition sizes and pivot selection methods for Quicksort, and the effect of using a Natural Merge Sort. Which factor has the most effect on the efficiency? Be sure to consider both time and space efficiency. Be sure to justify your data structures. Your analysis must include a table of the comparisons and exchanges observed and a graph of the asymptotic costs that you observed compared to the theoretical cost. Be sure to justify your choice of iteration versus recursion. Consider how your code would have differed if you had made the other choice.
Answers
The necessary conditions and procedures needed to accomplish this assignment is given below. Quicksort is an algorithm used to sort data in a fast and efficient manner.
What is the Quicksort?Some rules to follow in the above work are:
A)Choose the initial element of the partition as the pivot.
b) Utilize the same method to select the pivot, but switch to insertion sort as the concluding step for partitions that contain 100 or fewer elements.
Lastly, Utilize the same method of pivot selection, but choose insertion sort for partitions that are of a size equal to or lesser than 50 in order to accomplish the task.

Initialize the arrays in (a) and (b) above, write java statements to determine and display the highest sales value and the month in which it occured. Use the JoptionPane class to display the output
Answers
To determine and display the highest sales value and the month in which it occurred, you can use the following Java code:
Program:
import javax.swing.JOptionPane;
public class SalesAnalysis {
public static void main(String[] args) {
int[] sales = {1200, 1500, 900, 1800, 2000};
String[] months = {"January", "February", "March", "April", "May"};
int maxSales = sales[0];
int maxIndex = 0;
for (int i = 1; i < sales.length; i++) {
if (sales[i] > maxSales) {
maxSales = sales[i];
maxIndex = i;
}
}
String output = "The highest sales value is $" + maxSales +
" and it occurred in " + months[maxIndex] + ".";
JOptionPane.showMessageDialog(null, output);
}
}
In this illustration, the arrays "sales" and "months" stand in for the relevant sales figures and months, respectively. These arrays are initialised using sample values.
The code then loops through the'sales' array, comparing each value to the current maximum sales value. If a greater value is discovered, the'maxSales' variable is updated, and the associated index is recorded in the'maxIndex' variable.
The highest sales value and the month it occurred in are presented in a message dialogue that is shown using the 'JOptionPane.showMessageDialog' function.
When this code is run, a dialogue box containing the desired output—the highest sales amount and the matching month—is displayed.
