By using a linked list data structure, we can handle the dynamic data very easily. Also, by using the Linked list data structure, we can make the manipulation very fast because it works on the concept of nodes. But sometimes, it is not feasible with data search operations. We have a di...
By using the above syntax we create a new node, here we use the malloc function to create a new node with the size of the node. After that, we use the pointer concept to create a new node and point to the next and previous node in the circular linked list. In this way, we can ...
Now that the structure of a node is ready to be used, a linked list data structure can be implemented using the concept of classes in C++. The most important element of the singly linked list is the first element in the list, commonly referred to as the head element. This is because ...
Iterator End( List* lst ) { return lst->sentry; } As you can see, the sentry node also doubles as the 'one past last' marker. If you are unfamiliar with the 'iterator' concept, the begin marker points to the first item, ...
now, an important concept: a pointer is just a variable. there are special functions that work with it, but its just an integer, really. That the integer it holds happens to be an offset in ram isnt terribly important for the moment (its important, but not for what I am trying to sa...
Lets take list {A, C}. We want to insert B. List is not empty and B can't go before A, so we go to the else: 1. current = A 2. There is something after A and A<B 3. current = C 4. There is nothing after C 5. B->next = NULL 6. C->next = B In other words,...
Did you anytime know how arrays & Linked Lists are popularly used data structures ? ? If NO then Interview oriented Arrays & LinkedList in C & C++ is good to start with. About this Course: 1. This Course Covers in depth Arrays & Linked List with its applications concept wise and practic...
linked list is a dynamic and linear data structure. The Concept Of Link List Link list used for the dynamic memory allocation. Array and link list both are the linear data structure. When we want to represent several lists by using arrays of varying size, either we have to represent. ...
sequence table, linked list:physical structure, he is to realize a structure on the actual physical address of the structure. For example, the sequence table is implemented as an array. The linked list uses pointers to complete the main work. Different structures have different differences in dif...
I guess I got the concept except one thing: When I set temp=head, for me it's like temp will point to NULL if the link list is empty and point to something different from NULL in case there's one element. But in the code says that if(temp->returnNext()==NULL) there's one ...
