O(n)

Understanding Time Complexity

When using Digital PR to build links, it's important to understand how the effort and results grow as you increase your outreach or content volume.

We want to know how the time and work needed change when you try to get more links.

Scenario Under Consideration

Analyze the time complexity of the following Digital PR outreach process.

// Pseudocode for Digital PR link outreach
for each journalist in list_of_journalists:
    create personalized pitch
    send email pitch
    if journalist responds positively:
        follow up and build relationship
        secure link placement

This code represents reaching out to journalists one by one, personalizing each message, and following up to get links.

Identify Repeating Operations

Look at what repeats as the input grows.

• Primary operation: Looping through each journalist to send pitches.
• How many times: Once for every journalist in the list.

How Execution Grows With Input

As you add more journalists, the number of emails and follow-ups grows directly with that number.

Input Size (n)	Approx. Operations
10	About 10 personalized emails and follow-ups
100	About 100 personalized emails and follow-ups
1000	About 1000 personalized emails and follow-ups

Pattern observation: The work grows in a straight line as you add more contacts.

Final Time Complexity

Time Complexity: O(n)

This means the time needed grows directly in proportion to the number of journalists you contact.

Common Mistake

[X] Wrong: "Adding more journalists won't increase my work much because I can send the same email to all."

[OK] Correct: Personalized outreach takes time for each contact, so work grows with each added journalist.

Interview Connect

Understanding how your outreach effort scales helps you plan realistic campaigns and shows you can think about workload growth clearly.
