What data structures do you know?

Main data structures that I know and use:

• Arrays — fixed size, store elements of the same type.
• Slices — dynamic arrays with resizable capacity (specific to Go).
• Linked lists — a sequence of elements where each contains a reference to the next.
• Hash tables (maps in Go) — associative arrays for quick access by key.
• Stack — a structure with LIFO access.
• Queue — a structure with FIFO access.
• Trees — hierarchical structures, e.g., binary search trees.
• Heaps — specialized trees for priority queues.

In Go, slices and maps are frequently used, and for more complex structures, you can implement your own types or use packages from the standard library.
