Solution: Sliding Window Median

Explore solving the sliding window median problem by using a dual heap approach combined with a hashmap to maintain balance and optimize median retrieval within a moving window. Understand how to implement max and min heaps to handle dynamic data efficiently and how to rebalance these structures as elements slide through the window. This lesson provides a clear explanation of time and space complexities while illustrating a practical approach to handling median calculations over subarrays.

We'll cover the following...

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 $10^{-5}$ of the actual value will be accepted.

Constraints:

$1 \leq$ k $\leq$ nums.length $\leq 10^3$
$-2^{31} \leq$
