• LC 53. Maximum Subarray
• LC 918. Maximum Sum Circular Subarray
• LC 978. Longest Turbulent Subarray
• LC 219. Contains Duplicate II

Day 5: May 26th, 2024

Today's Progress:

• Learnt about the fundamental cloud services that one essentially needs
• Spent the last 2 days wrapping up my last reports for college.

Thoughts: Realised how Cloud services actually function - while some of the services are definitely creative solution, a lot of them are essentially just wrapper classes of the infrastructure and other open source technologies, all have been abstracted somewhere away from the user so that the developer does not have to worry about those complications while scaling their product or application.

Day 3: May 22, 2024

Today's Progress:

• Learnt about Database sharding, difference between horizontal and vertical partitioning, along with drawbacks of sharding and how to overcome them
• System Design of Tinder

Thoughts: prepared how to ans database sharding related questions during interview, However, solving a complete system design question like tinder design still feels like I need a few more days to brush up my skills before I can do that effortlessly for interview.

Day 2: May 21, 2024

Today's Progress: Revised the OSI model, learnt how to define session and presentation layer for interviews...

Thoughts: Good revision, feel like session presentation layer is not that important for college, since it's rarely spoken about, but might be useful for interviews for network engineering roles. Glad I found Hussein Nasser's playlist

Day 1: May 20, 2024

Today's Progress: Started Gaurav Sen's playlist of System Design, learned about Load Balacing, Consistent Hashing and Monolithic architecture vs Microservices architecture.

Thoughts: Good start, I wanna try and be able to think for myself and come up with my own solution during system design interviews. Gaurav Sen's Playlist looks like a good place to start
