Grokking the coding interview equivalent leetcode problems

# GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

If link isn't working , then go to libgen (generally libgen.is) and search for the course there....the extracting method remains the same.

This is awesome, thanks! Have you seen the system design interview somewhere?

No but if you do, kindly share.

I found this: https://github.com/donnemartin/system-design-primer
Some people mentioned it's inspired by grokking, but I wouldn't know.

Awesome list!

For Cyclic Sort, you have the last item in the list linked to https://leetcode.com/problems/kth-missing-positive-number/ which is not correct.

The leetcode question has an array of sorted, positive numbers and you are looking for the kth missing positive. This is an LC easy and you don't even need cyclic sort since the numbers are already sorted.

The grokking question is an unsorted array containing both positive and negative numbers, possibly duplicate values, and you are finding all values from 1-k. This is a LC hard (per grokking)

There is a new grokking course on Educative. I am creating a new mapping. Pull requests are appreciated. Link: https://github.com/navidre/new_grokking_to_leetcode

If you feel bad for the author pay \$79 for lifetime access. There is a 20% off coupon so its \$63.20. https://designgurus.org/course/grokking-the-coding-interview

I bought the course a couple months ago for full price and all I can say is that I regret buying it and feel it was a waste of money. For how much it costs for what is basically a curated LeetCode problem set with solutions, a significant amount of the solutions don't offer much in depth or detailed explanation and some of the solutions fail to pass their closest LC equivalent problems. I've found better solution explanations and help from looking on the Discuss page of those LC problems and watching NeetCode's video solutions.

Hi,

I do see a couple of new patterns in the Grokking the Coding Interview: https://www.designgurus.io/course/grokking-the-coding-interview

Does anyone have the list of equivalent LC questions, especially under Multi-threaded?

Thanks to everyone.

You're the goat!

@i-zanis topological orderings are not unique right?

yes .. they may vary

### anand27 commented Dec 9, 2023
