5 Steps in Problem Solving

January 19, 2021

Assalamualaikum 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

So this is 5 steps in problem solving.

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)

To calculate

To determine

Step 2 : Design a solution

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

Step 4 : Testing (Compile and run)

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 :
