# Applications, Advantages and Disadvantages of Red-Black Tree

**Red-Black Tree** is one type of self-balancing tree where each node has one extra bit that is often interpreted as colour of the node. This bit (the colour) is used to ensure that the tree remains balanced.

__Properties of Red-Black Trees:__

Red-Black Trees have the accompanying properties:

- Each hub has a variety.
- The root is black.
- Each leaf is an exceptional hub called NIL (with no key).
- In the event that a hub is red, its youngsters are black [i.e., no 2 red adjacent nodes ]
- Each way from root to leaf has a similar number of black nodes.

__Coloring in Red Black Trees:__

- Each tree node is shaded either red or black.
- The root node of the tree is black all the time.
- Each way from the root to any of the leaf hubs should have similar number of black nodes.
- No two red nodes can be adjacent, i.e., a red node can’t be the parent or the offspring of another red node. Each tree

__Applications of Red-Black Tree:__

RB trees ensure, comparable to different calculations, ideal computational times for INSERT, DELETE and SEARCH activities. This reality permits their utilization in delicate applications according to the perspective of calculation time, for example, continuous applications.

Notwithstanding, because of their qualities, we can likewise utilize RB trees as crucial structure blocks in information structures fundamental for various applications.

- AVL Trees
- Tango Trees
- Functional Programming
- Java
- Computational geometry
- Linux Kernel
- Machine Learning
- Database Engines
- Operating systems
- File systems
- Symbol tables in compilers

__Real-time application of red-Black Tree:__

- RB trees are utilized in practical programming to build affiliated exhibits.
- In this application, RB trees work related to 2-4 trees, a self-adjusting information structure where each hub with kids has either two, three, or four kid hubs. For each 2-4 tree, there are comparing RB trees with information components in a similar request. It’s feasible to show that
**INSERT**and**DELETE**procedures on 2-4 trees are comparable to variety of flipping and turns in RB trees. - This outcome is summed up to exhibit that RB trees can be isometric to 2-3 trees or 2-4 trees, an outcome because of Guibas and Sedgewick (1978).

__Advantages of Red-Black Tree:__

- Red-black trees balance the level of the parallel tree.
- Red-black tree gets some margin to structure the tree by reestablishing the level of the parallel tree.
- The time intricacy for search activity is O(log n)
- It has similarly low constants in a wide scope of situations.
- Red-black trees are dynamic in nature.
- Red-black trees are relatively easy to implement and understand.
- Red-black trees can reduce the time it takes to search for a specific item.

__Disadvantages of Red-Black Tree:__

- Complicated to use due to all the activity edge cases; generally you’d need to utilize a standard library execution (for example: TreeSet in Java, STL set in C++, and so forth) instead of carrying out one yourself without any preparation.
- On the off chance that you plan to just form the tree once and just perform read activities from there on, AVL trees offer better execution. (By and by, this presentation gain is normally irrelevant, so most well-known standard libraries just give a red-dark tree execution and no AVL tree execution.)
- Since B-trees can have a variable number of children, they are regularly liked over red-black trees for ordering and putting away a lot of data on plates, since they can be kept somewhat shallow to restrict circle tasks.
- Locking red-black trees perform inefficiently with simultaneous access compared to locking skip lists, which (1) very fast even with simultaneous access; (2) are frequently less difficult to carry out; and (3) offer basically all the advantages of locking red-dark trees.
- Red-black trees are difficult to manage as the number of nodes in the tree increases.
- Insertions in red-black tree can be relatively slow compared to other data structures like AVL Tree.
- Not suitable for large datasets.
