This will be a series where I tackle questions that get asked at top-tier tech companies. I'll share how I think about the problems, what methods I use, and coding tricks I use.
Today's topic tackles Top K Biggest Numbers in an array. This is a common coding interview question used across many tech companies.
This question is interesting because there are many, many ways of solving it, each with its pros and cons. It's up to you as the algorithm designer to determine which algorithm will work for you.
I found this article very useful to help understand in more detail:

I dont think that coding interviews need to be about quizzes or brain teasers. Todays video focuses on a coding question that gives the candidate opportunities to demonstrate different skills: coding, problem solving, understanding of data structures and algorithms, and how to apply all the above in a practical setting. Lets dive into how to merge N sorted lists!
Before diving deeper, well start with a smaller subproblem, and see if we can glean any insights into merging N sorted lists.
