Introduction to problem solving

1. Problem Solving Cycle

   • 1. Analyze the problem
     • Understand the problem well
     • Analyze the problem
   • 2. Developing the algorithm
     • Think of possible solutions
     • Follow modular aproach while designing most appropriate solution
     • Identify operations for solution
   • 3. Coding
     • Code program using appropriate control structures
   • 4. Testing and Debugging
     • Test and debug program
     • Complete Documentation
   • 5. Implementation and Maintain
     • Implement code
     • Maintain program
   • Tools for representing algorithm
     • Algorithm
       • Definition
         • To write a logical step-by-step method to solve the problem is callled algorithm
     • Flow chart
       • A flowchart is the graphical or pictorial representaion of algorithm with the help of different symbols, shapes and arrows in order to demonstrate a process or a program
       • Symbols
     • Pseudocode
       • Defintion
         • A Pseudocode is a step-by-step description of an algorithm in code like structure using plain English text.

2. Decomposition

   • Decomposition is the process of breaking down a complex problem or system into smaller, more manageable parts. This allows for easier analysis, programming, and maintenance of the overall system
