# Data structures

In the updated version of the maTH library, we can also use historically well-known data structures, as shown in the table below.

| Data structure | Description                 | Source                                                   |
| -------------- | --------------------------- | -------------------------------------------------------- |
| Stack          | Simple, LIFO type structure | [Stack](/math/reference/data-structures/round.md)        |
| Queue          | FIFO type structure         | [Queue](/math/reference/data-structures/round-1.md)      |
| LinkedList     | Pointer based structure     | [LinkedList](/math/reference/data-structures/round-2.md) |
