Solution: Sliding Window Median

Explore how to solve the sliding window median problem using an optimized heap-based approach. Learn to maintain balanced max and min heaps, efficiently update medians as the window slides, and manage element removal with a hash map to reduce complexity. This lesson equips you with practical techniques to handle dynamic data in coding interviews.

Statement

Given an integer array, nums, and an integer, k, there is a sliding window of size k, which is moving from the very left to the very right of the array. We can only see the k numbers in the window. Each time the sliding window moves right by one position.

Given this scenario, return the median of the each window. Answers within 10510^{-5} of the actual value will be accepted.

Constraints:

  • 11 \leq k \leq nums.length 103\leq 10^3
  • 231-2^{31} \leq
