[rsrbk]

Fixes #1

[coderabbitai]

Walkthrough

The product_except_self function in product_of_array_except_self.py has been optimized to improve its time complexity from O(n^2) to O(n). This was achieved by pre-calculating left and right products for each element in the array, ensuring a more efficient computation.

Changes

Files	Change Summary
product_of_array_except_self.py	Optimized product_except_self function to calculate the product of all elements except the current one using pre-calculated left and right products.

Assessment against linked issues

Objective	Addressed	Explanation
Optimize time complexity to O(n) [#1]	✅

In code's embrace, we found a way,
To trim the time, make functions sway.
With left and right, we did contrive,
A swifter path, our code's alive.
Now O(n) is where we stand,
Efficiency at our command. 🌟

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.

5-6: Initialization of left_product and right_product arrays.

This change is crucial for achieving the desired O(n) complexity by storing pre-computed products.

---

8-9: Loop to compute left products.

Efficient use of previous computations to fill the left_product array.

---

11-12: Loop to compute right products.

Similar to the left products, this loop efficiently calculates the right products in reverse order.

---

15-16: Final computation of the result using pre-computed products.

This step combines the left and right products to achieve the final result in O(n) time complexity.
