Problem #25 Read Until Age Between 18 and 45

Introduction

In this tutorial, we will explore how to read a problem statement that asks for a solution involving ages between 18 and 45. This is a common type of programming challenge that tests your understanding of conditional logic and data processing. By following these steps, you will learn how to effectively approach and solve such problems.

Step 1: Understand the Problem Statement

• Read the problem statement carefully.
• Identify the key elements:
  • Age range: 18 to 45.
  • Any specific conditions or requirements mentioned in the problem.
• Clarify what is being asked. Are you to count, filter, or perform some operation based on ages?

Step 2: Determine Input and Output Requirements

• Identify the input format. For example:
  • Is it a list of ages?
  • Does it include other data, like names or IDs?
• Define the expected output:
  • Should you return a count of how many ages fall within the range?
  • Are you required to list those ages or perform calculations?

Step 3: Plan Your Approach

• Decide on the programming constructs to use:
  • Loops for iterating through lists.
  • Conditionals to check if an age falls within the range.
• Sketch a rough algorithm:
  • Initialize a counter or a list.
  • Loop through the ages and apply the conditions.

Step 4: Implement the Solution

Here is a sample code snippet in Python that demonstrates how to filter ages:

def filter_ages(age_list):
    filtered_ages = []
    for age in age_list:
        if 18 <= age <= 45:
            filtered_ages.append(age)
    return filtered_ages

• This function takes a list of ages and returns a new list containing only those ages that are between 18 and 45.

Step 5: Test Your Solution

• Create test cases to validate your solution:
  • Input: [15, 20, 30, 47, 22]
  • Expected Output: [20, 30, 22]
• Run your function with the test cases to ensure it behaves as expected.

Conclusion

In this tutorial, we covered how to approach a programming problem involving ages between 18 and 45. We discussed understanding the problem statement, determining input and output requirements, planning your approach, implementing a solution, and testing it. As a next step, you can practice with variations of this problem to strengthen your coding skills.
