Data Structures and Algorithms Quiz: Review and Practice

Study Notes

Introduction to Data Structure

Data structure is a fundamental concept in computer science
It deals with the organization, storage, and retrieval of data in a computer

Pointers and Dynamic Memory Allocation

Pointers are variables that hold memory addresses as their values
Dynamic memory allocation is a technique to allocate memory at runtime
It allows for efficient use of memory and enables the creation of dynamic data structures

Algorithm Definition and Characteristics

An algorithm is a well-defined procedure to solve a problem
Characteristics of an algorithm include:
- Finiteness: it must terminate after a finite number of steps
- Definiteness: each step is precisely defined
- Effectiveness: it can be performed by a computer
- Correctness: it produces the correct output

Algorithm Analysis

Algorithm analysis is the process of evaluating the performance of an algorithm
Two key metrics used in algorithm analysis are:
- Time Complexity: the amount of time an algorithm takes to complete
- Space Complexity: the amount of memory an algorithm uses

Asymptotic Notation

Asymptotic notation is a mathematical notation used to describe the time and space complexity of an algorithm
It provides a way to measure the performance of an algorithm as the input size increases

Types of Data Structure

Data structures can be classified into:
- Primitive data structures (e.g., integers, characters)
- Composite data structures (e.g., arrays, linked lists)
- Abstract data structures (e.g., stacks, queues)

Abstract Data Types (ADT)

An ADT is a high-level representation of a data structure
It defines the operations that can be performed on a data structure without specifying how it is implemented

Introduction to Arrays and Structure

An array is a collection of elements of the same data type stored in contiguous memory locations
A structure is a collection of elements of different data types stored in contiguous memory locations

Types of Array and Representation of Array

Arrays can be classified into:
- One-dimensional arrays
- Multi-dimensional arrays
Arrays can be represented in memory using:
- Row-major order
- Column-major order

Polynomial Representation and Evaluation

A polynomial is an expression consisting of variables and coefficients
Polynomial representation can be done using:
- Coefficient representation
- Array representation
Polynomial evaluation involves computing the value of a polynomial for a given input

Addition of Polynomial

Polynomial addition involves adding two or more polynomials
It can be performed using the following steps:
- Add corresponding coefficients
- Combine like terms

Self Referential Structure

A self-referential structure is a data structure that references itself
Examples of self-referential structures include:
- Linked lists
- Trees
