Project 10 C++ Create a Linkedi.ist Class: class LL public: LL O2 void InsertFront (ContactNode cn) i void InsertBack (ContactNode cn) void Printlist : private: 2 ContactNode head ContactNode tail: Write a program that: 1) Creates a linked 1ist of 50000 ContactNodes (from Contacts.h and Contacts.cpp). Insert each ContactNode to the front of the 1ist. Time how long it takes to insert all of the nodes into your linked ist 2) Creates a vector. Add 50000 Contacthodes (from Contacts.h and Contacts.cpp) to your vector by inserting them one at a time at the beginning of the vector. Your vector contains Contactlodes (not pointers to contact nodes). Time how long it takes to insert all of the nodes into your vector 3) Creates a vector. Add 50000 pointers to ContactNodes (from Contacts.h and Contacts.cpp) to your vector by inserting them one at a time at the beginning of the vector. Time how long it takes to insert all of the pointers into your vector include clock t begin, end double time spenti begin clock(); end clock ) time spent (double) (end-begin) CLOCK PER SEC Example output: Time creating linked list: (HIDDEN) Time creating vector: (HIDDEN) Time creating vector of pointers to contact nodes: (HIDDEN)
