|---|---|---|---|---|---|
| Indexing | Θ(n) | Θ(1) | Θ(1) | Θ(log n) | Θ(log n) |
| Insert/delete at beginning | Θ(1) | N/A | Θ(n) | Θ(log n) | Θ(1) |
| Insert/delete at end | Θ(1) | N/A | Θ(1) amortized | Θ(log n) | Θ(log n) updating |
| Insert/delete in middle | search time + Θ(1)[1][2][3] |
N/A | Θ(n) | Θ(log n) | Θ(log n) updating |
| Wasted space (average) | Θ(n) | 0 | Θ(n)[4] | Θ(n) | Θ(n) |
