Question 1

What is the sliding window algorithm?

Accepted Answer

The sliding window algorithm is a technique used to solve problems that involve a contiguous subarray or substring. It maintains a 'window' of a certain size that slides over the data structure, and the algorithm performs calculations on the elements within the window.

Question 2

What are the two types of sliding window problems?

Accepted Answer

Sliding window problems can be categorized into two types: fixed-size window and variable-size window. In fixed-size window problems, the size of the window is constant, while in variable-size window problems, the window size can change.
