serkan-ozal's 7th submission

[serkan-ozal]

• use smaller regions (increased region count) so there will be less idle time for the workers who completed their tasks
• get rid of some configuration related stuff during initialization which might save a few tens of milliseconds hopefully

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

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

• Execution time: 2.7s (It was 2.8s in the 6th submission in my testing env)

• Execution time of reference implementation: 5m 54.1s

Hi @gunnarmorling,

I have another one :) I am running out of ideas and trying to cut of a few tens of milliseconds (hopefully) by configuration changes. Let's see how it perform on the eval machine

Nice!
