        Algorthm design
        
        Developing a solution
        
        Debugging and testing
        
        Documentation
        
        Although it appears at the last stage of the problem-solving procedure, it should be carried
        out throughout the whole process.
        
        Describe in detail what a certain program is for and how it is desinged, developed and tested.
        
        Desinging
        
        The process of locating and fixing defects in a program
        
        The checking processes required to ensure that a program fulfils the purposes for which it
        was created
        
        Testing
        
        Ensure that a program works and is free of error
        
        There are various techniques we can adopt in developing a solution for a problem.
        
        Each module has a specification
        
        A module specification helps us understand how data is transmitted among modules.
        
        Includes
        
        Outputs (information retured)
        
        Processing steps (logic used)
        
        A description of inputs (data recieves)
        
        A finite sequence of steps arranged in specific logical order to generate a solution to a problem
        
        Two common ways to design and represent algorithms
        
        Pseudocode
        
        to represent an algorithm in narrative form
        
        Flow chart
        
        to represent the logic and actions of an algorithm graphically
        
        In-depth consideration of the identified problem
        
        Look into the problem from different perspectives in order to diagnose it correctly and
        gain a full picture of it.
        
        We can use an Input-Proces-Output Chart (IPO chart) to analyze the problem.
      - The initial step of solving a problem
      - Obtain a precise definition of the problem
      - Asking queation about the problem can help identify the problem more clearly.
