I had an itch to review the algorithms in Wikipedia strange, I knowand here are my notes:

With that please consider the following: List length is determined by reaching the last node, but you don't need it for this algorithm. There should be no reason to scan the list just to find a count that you don't need in the first place.

Your "finished" state is reached when the last segment of the bubble sort reaches a single node i. The secret to linked list or any other node-pointer pattern is the manipulation of the pointers. To that end, you can greatly utilize something you already use for manipulating your nodes: Never underestimate the power of a sheet of paper and a pencil to draw out how you want your algorithm to work.

Especially for something like this: Now take a look at the following considerably different approach. There is something within that is paramount to understanding the overall algorithm, but I'll save it for after the code: The purpose of this simple exercise is to establish that we're evaluating data, but we're actually sorting pointers.

Notice that except for p, which is always the head of the list, we use no additional pointers to nodes.

Instead we use pointers-to-pointers to manipulate the pointers buried in the list. To demonstrate how this algorithm works I've written a small test app that makes a random list of integers, then turns the above loose on said list.

I've also written a simple print-utility to print the list from any node to the end. Summary I strongly advise walking through the above algorithm with a debugger to understand better how it works. In fact, I advise that with most algorithms anyway, but algorithms that perform pointer-to-pointer actions can be a little daunting until you understand how powerful that really are.

This is not the only way to do this task, but is an intuitive approach if you think about how linked lists are managed, and how all you're really doing is changing values stored in pointers in predictable places.A ____list is a linked list in which every node has a next pointer and a back pointer.

You cannot write a recursive algorithm to implement the sequential search algorithm. false. The sorting algorithms bubble sort, selection sort, and insertion sort are O(nlog2n). Nov 15, · Bubble Sort takes an iterative approach — looping through elements in a matrix-like fashion — to sorting, and is a great place to start with implementing your first sorting algorithm.

(f) Performing a bubble sort on an array of n integers, in the worst case. (g) Displaying all n elements in a sorted linked list.

(h) Performing a binary search of a sorted array of n strings, in the worst case. 6. Perform a quicksort on the following list of integers. Show your work. Make sure you specify what happens with the pivot at each step. 0, 15, 7, 27, 4, 5 7.

Bubble sort is a simple and well-known sorting algorithm. It is used in practice once in a blue moon and its main application is to make an introduction to the sorting algorithms.

Bubble sort belongs to O(n 2) sorting algorithms, which makes it quite inefficient for sorting large data volumes.

In singly linked list i has installed 6 sorts:Interchange Sort, Bubble Sort, Selection Sort, Quick Sort, Merge Sort and Radix Sort. So i need everybody help me write 5 sorts: Insertion Sort, Binary Insertion Sort, Shaker Sort, Heap Sort, Shell Sort.

I am trying to use bubble-sort in order to sort a linked list. I use curr and trail in order to traverse thru the list.

curr is supposed to be one step ahead of trail always.
