Dijkstra’s shortest path algorithm finds the shortest path between nodes in a weighted graph, often used for navigation or network routing. According to foundational programming principles (e.g., Certiport Scripting and Programming Foundations Study Guide, Section on Algorithms), it is designed for problems involving optimal paths in graphs with non-negative edge weights.

Option A: "Given an increasing array of numbers, is the number 19 in the array?" This is incorrect. This is a search problem, typically solved by binary search for a sorted array, not Dijkstra’s algorithm, which deals with graphs.

Option B: "Given an alphabetized list of race entrants and a person’s name, is the person entered in the race?" This is incorrect. This is another search problem, solvable by binary search or linear search, not related to graph paths.

Option C: "Given two newspaper articles, what is the greatest sequence of words shared by both articles?" This is incorrect. This is a longest common subsequence (LCS) problem, solved by dynamic programming, not Dijkstra’s algorithm.

Option D: "Given the coordinates of five positions, what is the most fuel-efficient flight path?" This is correct. This describes a shortest path problem in a graph where nodes are positions (coordinates) and edges are distances or fuel costs. Dijkstra’s algorithm can find the most efficient path (e.g., minimizing fuel) between these points, assuming non-negative weights.

 During the design phase of an agile process, the focus is on determining the functions that need to be written. This involves understanding the user requirements and defining the system architecture to meet those needs. The design phase is iterative, allowing for continuous refinement and improvement of the design as more is learned about the system and its users. It’s a collaborative effort involving designers, developers, and stakeholders to ensure that the functions align with the goals of the project and the needs of the users.

A function definition is the blueprint for a block of code designed to perform a specific task. Here's what it includes:

Function Name: A unique name to identify and call the function (e.g., calculate_area).

Inputs (Parameters/Arguments): Values or variables passed into the function when it's called (e.g., width, height).

Outputs (Return Value): The result the function produces after processing (e.g., the calculated area). This value may or may not be explicitly returned.

Statements (Function Body): Contains the code that performs the actions and calculations within the function.
