The cheapest of the bunch if the Samsung Galaxy S26 base model, which bumps last year's S25 starting price by $100. But lucky for you, if you preorder it at Amazon, you'll not only get a free $100 Amazon gift card to make up for that price hike, but also a free storage upgrade. That means you'll get an unlocked Galaxy S26 with 512GB of storage and a $100 Amazon gift card all for $899.99. The offer ends on March 10, just one day before the official launch date. Just note your gift card may ship separately from the phone itself, so be on the lookout.
The quadtree is the two-dimensional case of a broader family of space-partitioning data structures. Octrees extend the same idea to three dimensions (splitting cubes into eight children), KD-trees use alternating axis-aligned splits (splitting along x, then y, then x again), and R-trees group nearby objects into bounding rectangles. Each variant makes different tradeoffs between construction time, query speed, and update cost.
