In general, algorithms that involve efficient data structure is applied in the following areas: numerical analysis, operating system, A. It refers how data is accessed, stored and retrieved. Using this scheme, data that was stored last should be the one to be extracted first. This also means that in order to gain access to the first data, all the other data that was stored before this first data must first be retrieved and extracted.

A queue is a data structure that can simulate a list or stream of data. In this structure, new elements are inserted at one end, and existing elements are removed from the other end. A binary tree is one type of data structure that has two nodes, a left node, and a right node. In programming, binary trees are an extension of the linked list structures. Recursion, is a function that calls itself based on a terminating condition, makes use of the stack. Using LIFO, a call to a recursive function saves the return address so that it knows how to return to the calling function after the call terminates.

A stack is a data structure in which only the top element can be accessed. As data is stored in the stack, each data is pushed downward, leaving the most recently added data on top. Moreover, both subtrees are also binary search trees. Multidimensional arrays make use of multiple indexes to store data.

It is useful when storing data that cannot be represented using single dimensional indexing, such as data representation in a board game, tables with data stored in more than one column.

It depends on where you intend to apply linked lists. If you based it on storage, a linked list is considered non-linear.

On the other hand, if you based it on access strategies, then a linked list is considered linear. Apart from being able to store simple structured data types, dynamic memory allocation can combine separately allocated structured blocks to form composite structures that expand and contract as needed.

Data has been inserted into the queue list the longest is the one that is removed first.

In a sequence of data, adjacent ones are merged and sorted to create bigger sorted lists. These sorted lists are then merged again to form an even bigger sorted list, which continues until you have one single sorted list. A variable that is given a Null value indicates an empty value. The void is used to identify pointers as having no initial size. A linked list is an ideal data structure because it can be modified easily. This means that editing a linked list works regardless of how many elements are in the list.

Pushing and popping applies to the way data is stored and retrieved in a stack. On the other hand, a pop denotes data retrieval, and in particular, refers to the topmost data being accessed. A linear search refers to the way a target key is being searched in a sequential data structure. In this method, each element in the list is checked and compared against the target key.

The process is repeated until found or if the end of the file has been reached. The amount of memory to be allocated or reserved would depend on the data type of the variable being declared. For example, if a variable is declared to be of integer type, then 32 bits of memory storage will be reserved for that variable. The heap is more flexible than the stack. However, the memory of the heap can at times be slower when compared to that stack.Its urgent send PDF in my email….
