Question 84

A monitoring system uses a sensor to measure signal frequency $f\,$ as an integer. The categorization algorithm is shown below:

1      f ← USERINPUT
2      IF NOT(f > 15) AND f MOD 4 = 0 THEN
3          OUTPUT "Alert"
4      ELSEIF NOT(f >= 8) OR f > 40 THEN
5          OUTPUT "Normal"
6      ELSEIF f MOD 5 = 0 THEN
7          OUTPUT "Critical"
8      ELSE
9          OUTPUT "Warning"
10     ENDIF

Which input value for $f\,$ would result in "Critical" being output by this algorithm?
