Assume that there is a 100 liter tank.
It is initially filled with just distilled water.
It is continuously drained at R liters per minute.
This tank is always maintained full and homogeneous by continuously adding and stirring R liters per minute of an unknown acid (or some fancy oil if it helps you solving this problem).
How many liters W of water will be in the tank after M minutes?
Neglect any expansion or contraction when the acid is mixed with water.
It makes no sense to speak of the mixture being part acid and part water. In fact the quantity of water is always 100, and the acid has a certain strength. It would have been better to get us to calculate the acid strength
Needs more test cases to disqualify the non-solutions that simply exploit the test-case space.
More test cases in the Test Suite is generally welcome, and also the threat of potentially adding (even) more cases in the future can deter hard-coded "non-solutions".
Most the leading solutions are just overfit the test cases, and meaningless.
Test 1 fails if the value is equal to result.
@Creator - Check the test suite
