C# Fork (adds random tests).

No random tests in C#

Directions say to round the final result to 2 decimal places, but some tests expect an exact, crazy-long decimal. SOS

I recommend returning and testing the result as a string. I tried different solutions that gave me errors like

Expected: 2.65, instead got: 2.65

even after rounding at the end, probably because slight differences in the way I rounded as compared to the test. With string comparison such errors cannot occur.

Note: partial liters should be managed.

It is not mentioned how.

Testing with 9 and 2.65
Should be exact - Expected: 22.66, instead got: 22.65

2 * 2.60 + 2 * 2.55 + 2 * 2.50 + 3 * 2.45 = 22.65

for PHP: the tests do not work - all tests were successful, no matter what code I wrote.

Please fix the tests.

JS random tests generate non-rectangular arrays.
