The change is based on feedback from discussion on Github mainly around filesystem cache bia in-between runs and ensuring correctness. * We now should run solutions against a bunch of input/output pairs of 1M rows each and verify that they produce the correct input and exit early if there is a failure. * We drop the Linux filesystem cache after syncing any dirty pages to Disk before each run. * The runner will now run for 10 times (5 more times) to ensure minimal variance, and also we will drop the two most outliers when counting the results (slowest and fastest solutions).

I will still need to test this on a live setting, and ensure that the changes are applied for all languages before we merge this. |

Will that mean solutions with an additional line in the end would fail ?

Why would they? (we still compare the trimmed version of both so it should be fine)

Just double checking, as some submissions (most?) are adding a new line at the end
