Study Notes
Abstract Data Types (ADT)
- ADTs describe sets of data.
- ADTs can be implemented using classes in programming languages.
- ADTs can be categorized as Static or Dynamic.
- Static ADTs change infrequently or not at all.
- Examples of Static ADTs include stacks, queues, trees, and graphs.
- Dynamic ADTs change frequently.
- Examples of Data Structures include arrays, linked lists, strings, structs, and classes.
Data Structures
- Data Structures show the relationships among data items using primitive structures or other data structures.
- Data Structures determine the amount of space required to store the ADT.
- Data Structures influence the efficiency of algorithms.
Example: School Environment
- Data is gathered to express knowledge about a specific environment.
- Data can be manipulated through operations like discussing, explaining, and calculating.
Stages of ADTs
- Specification defines data's components, properties, relationships, and operations.
-
Complex Data Structures are called composite data types.
- Arrays: Store data of the same type in contiguous memory spaces.
- Linked List: An ordered collection of data elements (nodes) where each element contains a reference to the next element.
- Strings: Sequences of characters.
- Structs: Group data and operations as a single data type.
- Classes: Define data and operations as a single data type.
Sample Problem
- The ABC Manufacturing Company wants to give a year-end bonus to its employees.
-
Data Properties:
- Employee Name (Characters)
- Employee Salary (Real Numbers)
- Employee Bonus (Calculated based on salary)
- Data Structure: Each employee's data can be stored in a node. Multiple nodes can be stored in an array.
-
Operations:
- Get Employee Names
- Get Employee Salaries
- Calculate Employee Bonuses
Algorithm
- An algorithm is a finite set of instructions that specify a sequence of operations to solve a specific problem.
- Algorithms use data structures for input, output, and intermediate computations.
- Algorithm Example: Finding the largest number in an unsorted list.
-
Properties of Algorithms:
- Finiteness: All instructions must terminate after a finite number of steps.
- Absence of Ambiguity: Each instruction must be clear and unambiguous.
- Sequence Definition: Steps or procedures must be grouped in a defined sequence.
- Input and Output Definition: Data and required results must be clearly defined.
- Scope definition: The scope of the problem must be defined before solving it.
- Effectiveness: Each step executes as expected in a finite amount of time.
- Efficiency: Solves the problem with minimal use of resources (time and space)
Algorithm Example: ABC Manufacturing Company
- The Algorithm will accept the names and salaries of five employees.
- It will then calculate the bonus for each employee based on the following criteria:
- If the employee’s salary is less than 5,000.00, the bonus is 50% of the salary.
- Otherwise, the bonus is 5,000.00.
- The algorithm will print the names and corresponding bonuses of the employees.
- The algorithm can be written in pseudocode first, and then implemented in a programming language.
- Once the algorithm is implemented, data structures and algorithms can be combined to form programs.
