Solution: Sliding Window Median

Explore how to solve the sliding window median problem by applying the heaps data structure pattern. Understand managing two heaps—a max-heap for smaller elements and a min-heap for larger ones—to find medians efficiently as the window slides. Learn balancing heaps and using a hash map to handle element removals with improved time complexity.

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
