There's a tradeoff: a lower capacity means you can skip more space during queries (you zoom in faster), but the tree has more nodes and uses more memory. A higher capacity means fewer nodes but each node requires checking more points linearly. As a starting point, capacities between 4 and 16 are reasonable defaults, though the best value depends on your data distribution and query patterns.
示例：nums = [2,1,2,4,3] → res = [4,2,4,-1,-1]。

I was days into my research before I finally found a clue. In an obscure document on the website of the International House of Pancakes Corporation there was a hint that the dark breakfast had been made. IHOP omelettes include pancake batter.

For content creators, this creates both opportunities and challenges. The opportunity is that appearing in AI-generated responses places your content in a prominent, trusted position that provides context and drives qualified traffic.
