I believe a lot of this is affected about how familiar idioms are used. The second example simplifies to me as something like "Loop to find the smallest", "check parity". The thing that seemed to take most of my cognitive capacity was the unstated assumption that 9999 was clearly bigger than any of the possible numbers. The first example did have a bit more complex condition, but it was fairly logical and not hard to understand. Again what bothered me was that there must have been a hidden way for the result of run_payroll(name, employee.salary) to pass its result to write_letter(name)
