Data Structure

  • Data structures are how data is methodically organized in a virtual system.
  • Data structure has a specialized format for organizing, processing, retrieving, and storing data.

Algorithm

  • Algorithms are procedures that solve a problem or perform a computation.
  • Algorithms act as an exact list of instructions, which are step by step.
  • Alternatively, algorithms have a set of rules to solve a problem or perform a task by taking an input, processing it, and producing an output.

Algorithm Examples

  • Finding the Largest Number requires taking three numbers as input, comparing the first number with the second, comparing the larger of the two with the third number and the final largest number is the output.
  • Deciding whether to bring an umbrella requires checking the weather forecast; taking if "rainy" or "cloudy," otherwise, do not take.

Differences Between Flowchart, Pseudocode, and Algorithm

  • A flowchart is a diagrammatic representation of steps in solving a problem.
  • Flowcharts use various symbols (ovals, rectangles, diamonds) to depict processes, decisions, and flow of control.
  • An algorithm is a procedure or the set of instructions designed to complete a specific task and written in a language-neutral manner using steps or statements.
  • Pseudocode is a plain language description of the steps in an algorithm, without programming language syntax, to illustrate logic clearly
  • Flowcharts visually understand the process flow, and identify potential delays or obstacles.
  • Pseudocode provides a human-readable representation of an algorithm, focusing on the major steps.
  • Flowcharts are used by designers to visualize the logic/process before coding.
  • Pseudocode helps translate an algorithm into a high-level description that programmers can easily convert into code.
