#### Conditional execution and Processing the Output Data

After we have the value of the quantity of water that has flown through the pipes, the next step is to compare that quantity with the volume of the pool itself.

We do that with a simple if-else statement, where the condition will be whether the quantity of water is less than the volume of the pool. If the statement returns true, we have to print one line that contains the ratio between the quantity of water that has flown through the pipes and the volume of the pool, as well as the ratio of the quiantity of the water from each pipe to the volume of the pool.

The ratio has to be in percent, that is why all the calculations so far will be multiplied by 100. The values will be inserted with placeholders and as there is a condition the result in percent to be formatted to two digits after the decimal point without rounding, we will use the method Math.Truncate(…).

However, if the condition returns false, that means that the quantity of water is more than the volume of the pool, therefore, it has overflown. Again, the output data has to be on one line, but this time it should contain only two values - the one of the hours when the worker was absent, and the quantity of water, which is the difference between the incoming water and the volume of the pool.
