Review management strategy in SEO Fundamentals - Time & Space Complexity

Time Complexity: Review management strategy

O(n)

Understanding Time Complexity

When managing online reviews, it is important to understand how the effort needed grows as the number of reviews increases.

We want to know how the time to handle reviews changes when more reviews come in.

Scenario Under Consideration

Analyze the time complexity of the following review management process.

// Pseudocode for managing reviews
for each review in reviews:
  check if review is positive or negative
  respond to review
  update review summary

This code goes through each review one by one, reads it, replies, and updates a summary.

Identify Repeating Operations

Look at what repeats as the number of reviews grows.

• Primary operation: Looping through each review to process it.
• How many times: Once for every review in the list.

How Execution Grows With Input

As the number of reviews increases, the time to manage them grows in a straight line.

Input Size (n)	Approx. Operations
10	30 operations
100	300 operations
1000	3000 operations

Pattern observation: Doubling the reviews doubles the work needed.

Final Time Complexity

Time Complexity: O(n)

This means the time to manage reviews grows directly with the number of reviews.

Common Mistake

[X] Wrong: "Responding to one review takes the same total time no matter how many reviews there are."

[OK] Correct: Each review needs individual attention, so more reviews mean more total time.

Interview Connect

Understanding how tasks grow with input size helps you plan and explain your approach clearly in real work situations.

Self-Check

"What if you batch process reviews instead of handling them one by one? How would the time complexity change?"
