+# Question 3: Simulating the Daily Temperature Changes in a Room
+
+## Scenario:
+
+Imagine a room where the temperature changes throughout the day. The room is divided into a 3x3 grid, where each cell represents a section of the room. The temperature in the room starts at a uniform value, but it changes based on the time of day. The goal is to simulate how the temperature changes in the room over a 24-hour period.
+
+## Problem Statement:
+
+You are required to write a program that simulates the temperature changes in the room.
+
+The program should:
+
+1. Initialize the temperature of the room.
+2. Use nested loops to update the temperature of each section of the room at each hour.
+3. Use if-else statements to apply the temperature changes based on the time of day.
+4. Print the temperature distribution in the room at each hour.
+5. Use a while loop to simulate the temperature changes over a 24-hour period.
+
+## Assumptions:
+
+- The room is a 3x3 grid.
+- The initial temperature of the room is 20°C.
+- The temperature increases by 1°C every hour from 6 AM to 6 PM.
+- The temperature decreases by 1°C every hour from 6 PM to 6 AM.
+- The simulation runs for 24 hours.
+
+## Instructions (for reference):
+
+1. Initialize a 3x3 grid representing the temperature of the room.
+2. Use nested loops to iterate through each section of the room.
+3. Use if-else statements to apply the temperature changes based on the time of day.
+4. Update the temperature of each section in the grid.
+5. Print the temperature distribution in the room at each hour.
+6. Use a while loop to simulate the temperature changes over 24 hours.
+
+## Deliverables:
+
+- A well-commented code that simulates the temperature changes in the room.
+- A brief explanation of how the code works.
+
+### Sample Output:
+
+Enter the Room Temperature: 30
+Enter the Number of Hours between 0-24: 3
+
