red–black tree

A red–black tree is like a game of jenga. It's like a tower made of colored blocks. red–black tree is a type of special tree where each block has a color, either red or black. The blocks are arranged in a specific order. Everything on the outside of the tower is black, and everything inside the tower alternates between red and black. All of the blocks are linked together in specific ways to make sure the tower stays balanced. When something is added or removed, the other blocks shift in the right way so that the tower stays standing. The structure helps keep the tower balanced and efficient.
