That depends on the design goals of the _if function. If the design goal is clarity and constraint to only work with procedures, then the _if function is fine. But if the design goal is flexibility and versatility, then your statement is correct.

Shorter description:

Create a function that removes specific bird species, known as 'geese', from a provided list.

Shorter/clearer description:

A bus makes several stops in the city, picking up and dropping off passengers at each stop.

You are given a list of pairs, where the first number represents passengers boarding at a stop,
and the second number represents passengers disembarking at that stop.

Your task is to find the number of passengers remaining on the bus after the last stop.

Keep in mind that the bus starts empty at the first stop and the result cannot be negative due to test case constraints.
