A red-black tree is a type of self-balancing binary search tree where each node contains an extra bit for denoting the color of the node, either red or black. This coloring helps maintain balance during insertions and deletions, ensuring that the tree remains approximately balanced and operations can be performed in logarithmic time complexity. The properties of red-black trees are closely tied to fundamental tree characteristics, such as height and depth, as well as the broader context of self-balancing binary search trees.
congrats on reading the definition of red-black tree. now let's actually learn it.
