πͺ Design a Parking Lot - System Design Interview Question
In a system design interview, you will be asked to design a complex system, such as a website, mobile app, or network infrastructure. The interviewer will evaluate your ability to decompose the problem into smaller subproblems, make trade-offs between different design decisions, and consider the scalability and performance of the final solution. The key to success in a system design interview is to clearly communicate your thought process and trade-offs, rather than getting bogged down in low-le...

π₯ Spark DataFrame Cache
In Apache Spark, you can cache a DataFrame in memory using the cache() or persist() method. The cache() method is a shorthand for persist() with the default storage level of MEMORY_ONLY. You can use the persist() method to specify a different storage level if desired, such as MEMORY_AND_DISK or MEMORY_ONLY_SER.

n Queens problem LeetCode 51
The n-queens problem is a well-known problem in computer science and mathematics that involves placing n chess queens on a n x n chessboard such that no two queens are able to attack each other. This means that no two queens can be placed on the same row, column, or diagonal. The problem can be generalized to other chess pieces, such as the n-rooks problem (where the goal is to place n rooks on the board such that no two rooks can attack each other) or the n-knights problem (where the goal is to...
