Study Notes
What is DSA?
- DSA stands for Data Structures and Algorithms.
- DSA refers to the study of methods for organizing and storing data and the design of procedures (algorithms) for solving problems that operate on these data structures.
- DSA is a crucial skill for computer science students, and those with good knowledge of DSA are often better programmers and more likely to pass tech giant interviews.
Importance of DSA
- DSA is essential for designing efficient algorithms and optimizing software performance.
Learning DSA
- To learn DSA, break the process into 5 parts, starting with learning a programming language.
- DSA consists of two interrelated parts: Data Structures and Algorithms.
- It is recommended to learn Data Structures first and then the related Algorithms.
Data Structures
- Data structures are essential components that help organize and store data efficiently in computer memory.
- Data structures provide a way to manage and manipulate data effectively, enabling faster access, insertion, and deletion operations.
- Common data structures include arrays, linked lists, stacks, queues, trees, and graphs, each serving specific purposes based on problem requirements.
Common Data Structures
- Array:
- A linear data structure that stores a collection of elements of the same data type.
- Elements are allocated contiguous memory, allowing for constant-time access.
- Each element has a unique index number.
- String:
- A sequence of characters, typically used to represent text.
- A data type that allows for the manipulation and processing of textual data in computer programs.
- Linked Lists:
- A linear data structure that stores data in nodes, which are connected by pointers.
- Unlike arrays, linked lists are not stored in contiguous memory locations.
- Matrix/Grid:
- A two-dimensional array of elements, arranged in rows and columns.
- Represented as a rectangular grid, with each element at the intersection of a row and column.
- Stack:
- A linear data structure that follows a particular order in which the operations are performed.
- The order may be LIFO (Last In First Out) or FILO (First In Last Out).
- Queue:
- A fundamental concept in computer science used for storing and managing data in a specific order.
- Follows the principle of “First in, First out” (FIFO), where the first element added to the queue is the first one to be removed.
- Heap:
- A complete binary tree data structure that satisfies the heap property: for every node, the value...
