serkan-ozal's 4th submission

[serkan-ozal]

• split big regions into shared smaller tasks, so the workers complete their own tasks can pick up from the remaining instead of leaving its core idle
• reduce number of executed instructions in the hot path

Check List:

• [x] You have run ./mvnw verify and the project builds successfully

• [x] Tests pass (./test.sh <username> shows no differences between expected and actual outputs)

• [x] All formatting changes by the build are committed

• [x] Your launch script is named calculate_average_<username>.sh (make sure to match casing of your GH user name) and is executable

• [x] Output matches that of calculate_average_baseline.sh

• [x] For new entries, or after substantial changes: When implementing custom hash structures, please point to where you deal with hash collisions (line number): 638

• Execution time: 3.2s/3.3s (It was 3.4s in the 3rd submission in my testing env)

• Execution time of reference implementation: 5m 54.1s
