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.

Pattern: Sliding Window

• https://leetcode.com/problems/maximum-subarray/ # Close enough
• https://leetcode.com/problems/minimum-size-subarray-sum/

// IMPORTANT! READ THIS FIRST
// Assisted Injection doesn't work with @HiltViewModel or @ViewModelInject
// Read more about the issue here: https://github.com/google/dagger/issues/2287

// AssistedInject and Hilt working together in v2.28-alpha times
// Example of a ViewModel using AssistedInject injected in a Fragment by Hilt
// As AssistedInject isn't part of Dagger yet, we cannot use in
// conjuction with @ViewModelInject
