Array and Strings - Top Interview Questions[Hard] (2/9) - Python

Array and Strings

Array and String type of questions were asked in interviews frequently. You will most likely encounter one during your interviews.

We recommend: Product of Array Except Self, Spiral Matrix, First Missing Positive, Longest Substring with At Most K Distinct Characters, Sliding Window Maximum and Minimum Window Substring.

The last three problems are a bit more challenging, so feel free to skip those and revisit later if you're stuck.
