About Me



Hey Friends!

I am MI Ansari, creator of this blog, a passionate programmer and blogger who likes to share everything he knows with other geeks of my kind family. I like to share my experiences and don't want anyone to stuck up in the problems which I have solution. The main aim of this blog to provide simple solutions to problem.

Please feel free to ask about yours problems and I am totally there not to solve but make you to solve the problem.

With Regards.

Link List

In computer science, a linked list is a linear collection of elements, called nodes, each node have info field and next field pointing to the next node by means of a pointer. It is a data structure consisting of a group of nodes in sequence and connected with links. In simplest form of this data structure, each node is consist of data and a reference (in other words, a link) to the next node in the sequence. This structure allows for efficient insertion or removal of elements from any position in the sequence during iteration. Types of Link List Singly Link List: Insert node at first position in singly link list Insert node at last position in singly link list Insert node at specific position in singly link list Delete node at first position in singly link list Delete node at last position in singly link list Delete node at specific position in singly link list Find number of nodes in singly link list Dublication of singly link list Concatenation of two singly link list So...

Insertion at specific position N in singly link list

Insertion of a new node at position N in singly link list requires traversing the list for N-1 th node so that links are updated to accommodate the new node in the list. The new node's next is set to point to Nth node of the list and then N-1 th node's next pointer is updated so that it reference to new node. The step by step algorithm to insert node at Nth position is as below: Algorithm to insert node at specific position N in singly link list: This algorithm will insert the new node PTR at the position N in the link list. The steps are as follows: Create new node PTR Set the INFO field of PTR If N is less than 1 Node can't be inserted Else If node is to be inserted at first i.e. [N=1] Make new node PTR points to first node i.e. [PTR->NEXT = START] Make START point to new node PTR i.e. [START = PTR] Else Traverse the list to get the (N-1)th node of list into TEMP Make PTR's next pointer point to Nth node in the list i.e. [PTR -> NEXT  =  TEMP-...

Deletion of first node in circular link list

Deletion of first node from the circular link list requires that the list has at least one node. It is error to delete a node doesn't exist. In this process, last node's next pointer is updated to point to second node of the list. Now we will see the algorithm to delete node at first position in circular link list. Algorithm to delete first node in circular link list: The algorithm uses TAIL as pointer to the last node of circular list and TEMP is temporary pointer that help in deletion process. The steps are as follows: Declare TEMP If list have only one node FREE (TAIL) TAIL = NULL Else TEMP = TAIL->NEXT  [TEMP will point to first node] TAIL->NEXT = TAIL->NEXT->NEXT [TAIL's next will now point to second node] Free (TEMP) [free the first node] End If; Function to delete node at first position in circular link list: The function takes pointer to last node as input and return info part of the list if no error occur, otherwise returns -1 after printi...
