What are data structures and why are they important?
Before we dive into the details of Tremblay and Sorenson's book, let us first understand what data structures are and why they are important for computer science. Data structures are ways of organizing and storing data in a computer memory so that they can be accessed and manipulated efficiently. Data structures can be classified into two types: primitive and abstract. Primitive data structures are the basic building blocks of data, such as integers, characters, booleans, floats, etc. Abstract data structures are more complex and sophisticated ways of organizing data, such as arrays, lists, stacks, queues, trees, graphs, etc.
Data structures are important for computer science because they enable us to solve various problems using different algorithms. Algorithms are sequences of instructions that perform specific tasks on data. Depending on the nature and complexity of the problem, different data structures may be more suitable or efficient than others. For example, if we want to store a large number of items in a sequential order and access them from both ends, we might use a queue data structure. If we want to store hierarchical or networked data that have parent-child or neighbor relationships, we might use a tree or a graph data structure. If we want to sort or search data quickly, we might use a hash table or a binary search tree data structure.
Definition and examples of data structures
As mentioned above, data structures are ways of organizing and storing data in a computer memory so that they can be accessed and manipulated efficiently. Here are some definitions and examples of common data structures:
An array is a collection of elements of the same type that are stored in contiguous memory locations. Each element can be accessed by its index or position in the array. For example, an array of integers can store 10 numbers from 0 to 9 as follows: [0, 1, 2, 3, 4, 5, 6, 7 ,8 ,9].
A list is a collection of elements that can be of different types and are stored in non-contiguous memory locations. Each element can be accessed by its pointer or reference to the next element in the list. For example, a list of strings can store three words as follows: ["hello", "world", "bye"].
A stack is a collection of elements that follow the last-in first-out (LIFO) principle. That means that the last element added to the stack is the first one removed from it. A stack can be implemented using an array or a list. For example, a stack of characters can store four letters as follows: [A,B,C,D]. The top element is D and the bottom element is A.
A queue is a collection of elements that follow the first-in first-out (FIFO) principle. That means that the first element added to the queue is the first one removed from it. A queue can be implemented using an array or a list. For example, a queue of numbers can store five digits as follows: [1 ,2 ,3 ,4 ,5]. The front element is 1 and the rear element is 5.
A tree is a collection of nodes that have parent-child relationships. Each node can have zero or more children nodes. There is one special node called the root node that has no parent node. A tree can be implemented using pointers or arrays. For example a tree data structure can store data such as family relationships, organizational hierarchy, file system, etc. For example, a family tree can store the names and generations of a family as follows:
John / \ Alice Bob / \ \ Carol Dan Eve
A node that has no children is called a leaf node. For example, Carol, Dan, and Eve are leaf nodes. A node that has at least one child is called an internal node. For example, John, Alice, and Bob are internal nodes. The height of a tree is the length of the longest path from the root to any leaf node. For example, the height of the above tree is 2.
Applications and benefits of data structures
Data structures are useful for solving various problems using different algorithms. Some of the applications and benefits of data structures are:
Data structures can help us store and organize data efficiently and compactly. For example, arrays can store data in a contiguous memory space, reducing the overhead of memory allocation and deallocation. Lists can store data dynamically, allowing us to add or remove elements without resizing the data structure.
Data structures can help us access and manipulate data faster and easier. For example, stacks can help us implement undo and redo operations by pushing and popping elements from the top. Queues can help us implement first-come first-serve policies by enqueuing and dequeuing elements from the front and rear.
Data structures can help us implement abstract data types (ADTs) that hide the implementation details and provide a clear interface for the users. For example, we can implement a priority queue ADT using a heap data structure that supports inserting and removing elements according to their priorities.
Data structures can help us optimize the performance and complexity of algorithms. For example, we can use hash tables to implement dictionaries that support fast lookup, insertion, and deletion of key-value pairs. We can use binary search trees to implement sorted sets that support fast searching, sorting, and ordering of elements.
Data structures can help us model real-world problems and phenomena. For example, we can use graphs to represent networks of nodes and edges, such as social networks, transportation networks, web pages, etc. We can use trees to represent hierarchical or recursive structures, such as file systems, expression trees, decision trees, etc.
