luckyq / packed-memory-array

A simple implementation of the packed memory array

Benchmarks

Implementation-1

Time to insert 10⁷ elements: 0m30.180s^*

Implementation-2

Time to insert 10⁷ elements: 0m25.048s^*

* (When compiled with -O2 using g++, on a 2.3 GHz Intel Core i7 machine with 8G RAM)

Analysis

• Complexity of an insert: O(log²n) (amortized)

• Complexity of find (binary search): O(log²n) (worst-case)
