How does a red-black tree ensure that it remains balanced after insertions and deletions?
- By assigning different colors (red or black) to each node and enforcing specific rules during insertions and deletions.
- By limiting the height of the tree to a constant value.
- By randomly rearranging nodes in the tree.
- By sorting nodes based on their values.
A red-black tree ensures balance by assigning colors (red or black) to each node and enforcing rules during insertions and deletions. These rules include properties like no consecutive red nodes and equal black height on every path, ensuring logarithmic height and balanced structure.
