I optimized my solution:

[yavuztas]

• Eliminate redundant object creations in between
• Custom HashMap on purpose - Inspired by @spullara
• More performant temperature parsing - Inspired by @yemreinci
• JVM tweaks, decreased heap memory, and remove AlwaysPreTouch

Check List:

• [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

• Execution time: ~3s
• Execution time of reference implementation: ~3m.22s

Hi @gunnarmorling I recreated my PR since there were some stubborn files, couldn't rebase for some reason. Please review this one, instead of the other. It should be closed though. Many thanks!
