in java we need to order a list , if we create a program in java what  are the possible ways of telling your program how to move the numbers in the list to make it sorted, where each way provides the required result.

list the name of sorting with short explanation

I want c++ /c program to build a double linked list and find with a function the middle element and its position and the linked list must be inserted by the user aand note You should handle the both cases of whether the size of the list even or odd

IN SCHEME

Write a function subtract which takes a list of numbers as a parameter and returns a list of the differences. So, a list containing the second minus the first, third minus the second, etc.

(subtract '(3 4 10 14 5))

'(1 6 4 -9)

Do it in python please

This lesson's Group Activities are:

We're going to take the Group Activity from last week and tweak it. Instead of storing the random numbers in a list, we're going to store them in a file. Write a program using functions and mainline logic which prompts the user to enter a number, then generates that number of random integers and stores them in a file. It should then display the following data to back to the user:

• The list of integers
• The lowest number in the list
• The highest number in the list
• The total sum of all the numbers in the list
• The average number in the list
• At a minimum, the numbers should range from 0 to 50, but you can use any range you like.

Helpful hint: don't forget about input validation loops and try/catch exceptional handling. Both are very useful when used in conjunction with functions.

#Write a function called wish_list. wish_list should have
#four parameters, in this order:
#
# - a list of strings, representing a list of items on a
# wish list
# - a string, representing a particular item
# - a float, representing the cost of this item
# - a float, representing your budget
#
#If the item is on the list and you can afford it (cost is
#less than or equal to budget), return the string,
#"You should buy a [item name]!", replacing [item name]
#with the string.
#
#If the item is on the list but you can't afford it,
#return the string, "You should save up for a [item name]!",
#replacing [item name] with the string.
#
#If the item is not on the list, you should return the
#string "You probably don't want to buy a [item name].",
#replacing [item name] with the string.
#
#HINT: You do not need a loop to solve this. You can use
#one, but you don't need one.

You are asked to delete the last occurrence of an item from a linked list. So, for instance:

Input: 2 -> 3 -> 2 -> 4

Delete last occurrence of 2, result: 2 -> 3 -> 4

Implement the following method to do the deletion. You may NOT use or implement helper methods - all your code must be implemented inside the given method. You may NOT use recursion.

public class Node {
public int data;
public Node next;
}

// Deletes LAST occurrence of given item from a linked list,
// given a front pointer to the first node in the list.
// Returns pointer to first node of the updated linked list.
// Input list could be empty.
// Throws NoSuchElementException if item is not in the linked
// list.

public static Node deleteLastOccurrence(Node front, int item)
throws NoSuchElementException {

// COMPLETE THIS METHOD

}

1. Write a python program to create a list of integers using random function. Use map function to process the list on the expression: 3x2+4x+5 and store the mapped elements in another list. Now use filter to do sum of all the elements in another list.

2. Write a function that takes n as input and creates a list of n lists such that ith list contains first 10 multiples of i.

3. Write a function that takes a number as input parameter and returns the corresponding text in word. For example, on input 458, the function should return ‘Four Five Eight’. Use dictionary for mapping digits to their string representation.

4. Write a program to create two sets of integer type using random function. Perform following operations on these two sets:

a) Union

b) Intersection

c) Difference

d) Symmetric difference

Through Python, a dictionary or list is often used to store a sequential collection of elements. Suppose, for instance, that you need to read 50 numbers, compute their average, and then compare each number with the average to determine whether it is below or above the average. In order to do this (without the use of list), you would first declare 50 variables to store the 50 numbers. This means you would have to create 50 variables and repeatedly write almost the identical code 50 times. Writing a program this way is impractical. To overcome this issue, you can make use of a list to store all the 50 numbers and access them through a single list variable.

For your initial post, describe the difference between dictionary and list in Python and explain when each would be used. Provide an example of how each dictionary and list would be implemented within Python. 250 WORDS

Please attach the output screenshots, narrative descriptions, or paste the Python codes when requested.

Task 2

Please define a function that extracts the even numbers in a given list. For example, given a list x = [2,3,5,6,7], the function will return a sublist [2,6] because 2 and 6 are even numbers in the list x.

The input of this function should be a list, and the output of the function should be a list as well (the sublist).

You can try the inline for loop with conditions to make the solution super simple.

Task 3

Use inline for loop to extract the common elements in two lists. For example, if x = [1,2,3], and y = [2,3,4], the result should be [2,3].

Hint: to check if a value exists in a list, you can use the “in” command. For example: we define two variables

a = 2 in [1,2,3]

b = 4 in [1,2,3].

After executing the codes, a will be a “True”, and b will be a “False”.

Use the attached UML diagrams to build up your project classes

Make sure to put view for your project by Entering true data

You will need to add 5 books and 5 students and at least 3 LibraryIssues

LibraryIssues keeps track of the borrowed book

The librray uses all classes as mentioned in the UML diagram

You will need to check if book is available before borrowing it.

searchLibrrayIssueByStuent(Student): List

This method returns all book if borrowed by single student, as a student could borrow more than one book

Static NUMBEROFBOOKS: int

Each time you add a book the static variable is increased  and Each time a book is removed so the static variable is decreased.

createLibraryIssue(LibraryIssue) : boolean

changed the Boolean variable status in book element to false and return false if book is not available

removeLibrrayIssue(LibraryIssue):Boolean

changed the Boolean variable status in book element to true and return false if book is available

Note

LibrrayIssue and Book in the class Library should be List or map

Do not use array as the size is not fixed
