I am telling you the algorithm of inserting an element at any location of simply link list:-


insert_loc(start,item,loc)

step1. [Check for overflow]
if ptr=NULL
then print overflow
exit
else
[ptr=(node*) malloc (size of nodes)] {memory allocation}

step2. set ptr->info=item
step3. set i=1
set temp=start
step4. Repeat step 5&6 until istep5. set temp=temp->next
step6. set i=i+1
step7. set ptr->next=temp->next
step8. set temp->next=ptr

Good luck

What is best and worst case of time complexity and space complexity of insert and delete operation in singly linked list doubly linked list?

When inserting or extracting at the end of a singly-linked list or at the beginning or end of a doubly-linked list, the complexity is constant time. Inserting or extracting in the middle of a list has linear complexity, with best case O(1) when the insertion or extraction point is already known in advance and a worst case of O(n) when it is not.


Algorithm in creating insert method in linked list?

You sort a doubly linked list the same way you sort any other kind of list or array. You implement a procedure to sort the list or array, and that procedure calls the appropriate insert, delete, or move methods of the list or array.


What are the purpose of an algorithm?

As described in the link, an algorithm (the word is based on the name of the Arabic scholar who developed the concept) is a finite list of steps that can be taken in order to solve a specific problem or to produce a certain result. It is important to note that an algorithm does not put you into an infinite loop. There is a path to a final conclusion. It was first developed as a set of procedures for doing arithmetic calculations. Algorithms can be pictured with familiar symbols (see link) like boxes, diamond shapes, circles, etc. connected by arrows showing various points of decision making, and what conclusions can be drawn if you end up at a given point (presuming you followed the 'flow' correctly, and answered the questions accurately-- and also presuming that the algorithm is rigorous.) Of course, the concept is easily applicable to all kinds of engineering and theoretical areas. Algorithms are 'heuristic', meaning that they are seen as basically unjustified, and incapable of justification in and of themselves. This is really a basic and very powerful idea. Heuristics are completely flexible, and they can grow and change as the various conclusions and outcomes are examined. nice answer

What is the worst-case scenario for the quicksort algorithm when using the middle element as the pivot?

The worst-case scenario for the quicksort algorithm using the middle element as the pivot occurs when the array is already sorted or nearly sorted. This can lead to unbalanced partitions and result in a time complexity of O(n2), making the algorithm inefficient.

Which algorithm is efficient for finding an element from a sorted list?

Basically you split the list in two, looking at the element in the middle of the list. If the list is in ascending order, and the element you are looking for is SMALLER than the element in the middle of the list, you repeat this procedure for the FIRST half of the list (again, splitting it in two); if it is LARGER, you repeat for the SECOND half of the list.


How to write a algorithm of inserting an element at middle of a linked list?

Assuming your new element is e and the list is L: - Find the node in L that you want to precede e, lets call it x, and the node following it y. So right now your list looks like: L->L+1->....->x->y->y+1->...->NULL e->NULL - Modify e's next pointer to point to x->next (in this case this equals y), so both x and e point to y L->L+1->....->x->y->y+1->...->NULL e->y - Modify x's next pointer to point to e: L->L+1->....->x->e->y->y+1->...->NULL


How can one perform a binary search?

One can perform a binary search easily in many different ways. One can perform a binary search by using an algorithm specifically designed to test the input key value with the value of the middle element.


What are the disadvantages of using a Binary Search?

The primary advantage of a binary search algorithm is that searching a sequence can be achieved in logarithmic time. The primary disadvantages are that the data must be in sorted order. Arrays are the ideal container for binary searches as they provide constant-time random-access and are therefore trivial to both sort and search efficiently. Sorted binary trees can also be used, however for optimal performance they must be totally balanced (e.g., red/black binary tree). Constant-time random-access is not a requirement of binary trees, however the cost of maintaining balance during construction of the tree has to be taken into account. With a linear search, we start at one end of the sequence and traverse through the sequence one element at a time until we find the value we're looking for, or we reach the element one-past-the-end of the sequence (in which case the element we're looking for does not exist). For a sequence of n elements, the worst case is O(n). Linear search is ideal for forward lists (singly-linked lists) and lists (doubly-linked lists) as neither provides nor requires constant-time random-access. With binary search, we locate the middle element in the sequence. If that's not the value we are looking for, we can easily determine which half of the sequence contains our value because the elements are in sorted order. So we eliminate the other half and repeat the algorithm with the remaining half. As such, each failure to find the value reduces the number of elements to be searched by half (plus the middle element). If there are no elements in the remaining half then the value does not exist. The worst case is therefore O(log n).

What is the binary search definition in computer science and how is it used to efficiently locate a specific element in a sorted array?

Binary search is a search algorithm in computer science that efficiently finds the position of a specific element in a sorted array by repeatedly dividing the search interval in half. This method is used to quickly locate the desired element by comparing it to the middle element of the array and eliminating half of the remaining elements each time, until the target element is found or determined to be absent.
