| Linked list | Array | Dynamic array | Balanced tree | Random access list | Hashed array tree | |
|---|---|---|---|---|---|---|
| Indexing | Θ(n) | Θ(1) | Θ(1) | Θ(log n) | Θ(log n)[1] | Θ(1) |
| Insert/delete at beginning | Θ(1) | N/A | Θ(n) | Θ(log n) | Θ(1) | Θ(n) |
| Insert/delete at end | Θ(1) when last element is known; Θ(n) when last element is unknown |
N/A | Θ(1) amortized | Θ(log n) | Θ(log n) updating | Θ(1) amortized |
| Insert/delete in middle | search time + Θ(1)[2][3] | N/A | Θ(n) | Θ(log n) | Θ(log n) updating | Θ(n) |
| Wasted space (average) | Θ(n) | 0 | Θ(n)[4] | Θ(n) | Θ(n) | Θ(√n) |
