PART- II
2. In assignment-1, you are asked to implement a similar phone book application, but you were not
supposed to use Binary Search Tree. Let’s compare the performance of search operations in both
solutions.
a. Perform a simple search operation with your solution in assignment-1, record the time
b. Perform a search for the same contact searched in (a) and record the time
c. Please compare your results.
Hint: you can record the execution time using the following code segment.
#include <ctime>
void calculateElapseTime() {
using namespace std;
clock_t begin = clock();
//code_to_time
clock_t end = clock();
double elapsed_secs = double(end – begin) / CLOCKS_PER_SEC;
}
Part-I Submission:
Please follow the following steps for each assignment:
1. Create a separate repository in GitHub
2. Clone the repository to your local computer.
3. Modify the files and commit changes to complete your solution in your local repository.
4. Push/sync the changes up to GitHub.
5. To turn in the assignment, send the link for the repository as an email to your instructor
([email protected])
Part-II Submission:
Please upload your answer as a text file to canvas for assignment-4.
