The problem description states:
For most accurate timing results, submission codes would include timing code to measure and print total execution time to stdout
What can be excluded from the total execution time, if anything?
Can we exclude time needed to:
- Construct a tbb::task_scheduler_init object
- Read the input file
- Construct an in-memory representation of the Masyu puzzle (this is part of parsing the input file)
- Write the solution (or a message that no solution exists) to the output file
