These lecture notes cover the key ideas involved in designing algorithms. We shall see how they depend on the design of suitable data structures, and how some structures and algorithms

Array Data Structure Guide. An array data structure is a fundamental concept in computer science that stores a collection of elements in a contiguous block of memory. It allows for efficient access to elements using indices and is widely used in programming for organizing and manipulating data.
Lecture Notes Chapter #6 Arrays. Array. solves the problem of storing a large number of values and manipulating them. is a data structure designed to store a fixed-size sequential collection of elements of the same type, i.e., it is a collection of variables of the same type. Array Declarations.
Arrays and Linked Lists: Arrays: Dynamic memory allocation, one-dimensional arrays, multidimensional arrays, operations on arrays, storage – Row major order, Column major order. Linked lists: types of linked lists – singly, doubly and circularly linked lists, operations on linked lists.
Single and Multidimensional Arrays: Array Declaration and Initialization of arrays – Arrays as function arguments. Strings: Initialization and String handling functions.
Following are the basic operations supported by an array. Traverse − print all the array elements one by one. Insertion − add an element at given index. Deletion − delete an element at given index. Search − search an element using given index or by value. Update − update an element at given index.
Common data structures and algorithms serve as “high level building blocks”. A power programmer: Rarely creates programs from scratch. Often creates programs using building blocks. Maintain a table of key/value pairs. Each key is a string; each value is an int. Unknown number of key-value pairs. Examples.
Example 3.5: Defining class to process arrays with any data type. void static reverseArray (T b) {// Generic method to reversed the order of elements in array b. int front = 0, rear = b. length-1; T temp; while(front < rear) {temp = b [rear]; b [rear] = a [front]; a [front] = temp; front ++; rear--;}}}
Lecture 2: Data Structures and Dynamic Arrays. Data structures are ways to store data with algorithms that support operations on the data. These collection of sorted operations are interfaces. This class goes over two main interfaces: sequence and set. Instructor: Erik Demaine.
