Comparison of list data structures
Linked list Array Dynamic array Balanced tree Random access list
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(n) when last element is unknown;
Θ(1) when last element is known
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)
