5 Steps in Problem Solving
January 19, 2021Assalamualaikum and hye everyone! Today we can learn 5 steps in prolem solving.
So, let's check out!
First and foremost we should learn about problem solving. So what is problem solving?
What is Problem Solving??
- Problem solving is the process of transforming the description of a problem into a solution.
- by using our knowledge of the problem domain and
- by relying on our ability to select and use appropriate problem solving strategies, techniques and tools
Step 1 : Problem Analysis (IPO analysis)
Step 2 : Design a solution (pseudocode and flowchart)
Step 3 : Implementation (coding)
Step 4 : Testing (Compile and run)
Step 5 : Documentation (Comment)
Step 1 : Problem Analysis (IPO analysis)
- An analysis of problem statement to identify:
- Output ( To find calculate)
- Input (What data is needed to get output)
- Process (Explanation of how to process data to get output)
- Process key word
To determine
Step 2 : Design a solution
- Design a solution involves creating an algorithm
- An algorith is a sequence of well-defined steps to solve a problem.
- Alogorithm can be represented using pseudocode or flowchart.
Step 3 : Implementation (coding )
- Implementation is the process of implementing an algorithm by writing a computer program using a programming language
- Eg : Using Java Langguage
- After you translate a designed algorithm into a Java program and compile it, you ready to run it.
- In this phase, your main objective is to convince that the program will do what it is expected to do
- In other words, you will want to verify that your program is correct.
- Program verication : Process of ensuring that a program meet user-requirement (ie: test/verify it with different inputs)
- One of the technique used for program verification is program testing
- Program testing : Process of executing a program to demonstrate its correctness (ie: run the program)
Step 5 : Documentation
- Contains description of the program that helps other programmers in editing or maintaining the program larer.
- Can be done in 2 ways :
- Writing comments between your lines of codes
- Creating a seperate text file to explain the program.
