Can you explain in detail, line by line, what the attached algorithm is doing? I need further understanding. For further clarification the prompt asks the following: Write an algorithm Replace that takes a stack and two items. If the first item is in the stack, replace it with the second item, leaving the rest of the stack unchanged.

Find out what happens when you just leave the stack alone.

Java Programming language Please help me with this. Thanks in advance.

Quick Sort We choose an element from the list, called the pivot. We'll use it to divide the list into two sub-lists. We reorder all the elements around the pivot The ones with smaller value are placed before it All the elements greater than the pivot after it. After this step, the pivot is in its final position. This is the important partition step. We apply the above steps recursively to both sub-lists on the left and right of the pivot.   Quick Sort (Example) Consider the following array Arr[] = {5, 9, 4, 6, 5, 3} Let's suppose we pick 5 as the pivot for simplicity We'll first put all elements less than 5 in the first position of the array: {3, 4, 5, 6, 5, 9} We'll then repeat it for the left sub-array {3,4}, taking 3 as the pivot There are no elements less than 3 We apply quicksort on the sub-array in the right of the pivot, i.e. {4} This sub-array consists of only one sorted element We continue with the right part of the original array, {6, 5, 9} until we get the final ordered…

I have implemented a stack using arrays. The array is 5 elements long and is called examstack. The contents are: examstack[0] = 36 examstack[1] = 49 examstack[2] = 7 examstack[3] = 67 examstack[4] = 9 If I did a Pop what would be returned? 9 or 36 09 07 O 67 O 9 or 67 36 or 49 O 36 49

ORIGINAL Q: Instead of reading in an entire list N1,N2,⋯N1​,N2,⋯​ all at once, some algorithms (depending on the task to be done) can read in only one element at a time and process that single element completely before inputting the next one. This can be a useful technique when the list is very big (e.g., billions of elements) and there might not be enough memory in the computer to store it in its entirety. Write an algorithm that reads in a sequence of values v≥0, one at a time, and computes the average of all the numbers. You should stop the computation when you input a value of V = −1. Do not include this negative value in your computations; it is not a piece of data but only a marker to identify the end of the list. PLEASE MODIFY THE FOLLOWING CODE SO THE USER INPUTS THE NUMBERS ONE BY ONE: ORIGINAL Q: Instead of reading in an entire list N1,N2,⋯N1 ,N2,⋯ all at once, some algorithms (depending on the task to be done) can read in only one element at a time and process that single…

Use Java : Delete N Nodes After M Nodes of a Linked List You are given the head of a linked list and two integers m and n.Traverse the linked list and remove some nodes in the following way:- Start with the head as the current node.- Keep the first m nodes starting with the current node.- Remove the next n nodes- Keep repeating steps 2 and 3 until you reach the end of the list.Return the head of the modified list after removing the mentioned nodes
