Study Notes
Data Structures and Algorithms Overview
- A linear array does not track the address of every element in the list.
- An AVL tree is a binary search tree where the left and right subtrees differ in height by at most 1 unit.
- A linked list is classified as a dynamic data structure that allows for flexible memory usage.
- Posterior analysis is deemed more accurate than a priori analysis because it relies on real data obtained through reverse engineering.
- Arrays are optimal data structures for relatively permanent collections of data that undergo infrequent changes.
Algorithms and Performance
- An already sorted array performs best with the Insertion sort algorithm.
- Inserting an item into a stack is called a "push" operation, while deleting an item from an empty stack is called a "pop" operation.
- The maximum number of spanning trees in a connected graph can vary, with specific conditions affecting this.
- Shell sort utilizes insertion sort as its underlying algorithm.
- The logical or mathematical model representing a data organization is referred to as a data structure.
Graph Theory and Time Complexity
- Dijkstra's single-source shortest path algorithm has a time complexity of O(|E| + |V| log |V|) when implemented with an adjacency list and a binary heap.
- The top value of a stack changes during the deletion operation, impacting stack underflow checks.
- There are three levels of data structure implementation: application level, abstract level, and implementation level, encompassing all.
Abstract Data Types (ADT)
- An ADT description consists of both data and operations; the absence of either does not constitute a complete description.
- Characteristics of abstract data types include exporting a set of operations and exporting a type, which can vary regarding their truthfulness.
- Recursive design is critical for certain algorithms, highlighting its importance in data structure creation and manipulation.
