QuestionsTwo HeapsSliding Window Median

Sliding Window Median

HARD

Master this problem using the Two Heaps pattern.

Solve on LeetCode
Pattern: Two Heaps
Pattern Intuition & Strategy

When approaching Sliding Window Median, look for key problem signals that suggest using the Two Heaps pattern. Focus on reducing redundant iterations, maintaining state invariant, and optimizing space-time complexity.

Key Invariant

Maintain optimal range bounds or hash frequency state during traversal.

Expected Complexity

Time: O(N) or O(N log N) | Space: O(1) to O(N)
