Write my research paper
Use a simple vector you created before to create two other more complex vectors with A) Memory allocation that doubles size of memory when end reached, and 1/2s memory when the size reaches 1/4. B) Implemented with a singularly linked list.Main.cpp#include
#include SimpleVector.h
