How many breaks does the shift need
Labour law requires a 30-minute rest after every four hours on the floor. Count the mandatory breaks a shift of lengthMinutes earns.
- Four full hours (240 minutes) earns the first break, eight hours the second, and so on.
- A shift of exactly 240 minutes gets one break, not two.
breakCount(lengthMinutes: int) → int
Java needs a compiler and Drill does not host one yet, so this page is the reference rather than an exercise: the problem, worked examples, and the solution in full. To type it out, the same problem runs in Python.
Where you start
int breakCount(int lengthMinutes) {
}Worked examples
| Call | Result |
|---|---|
breakCount(120) | 0 |
breakCount(240) | 1 |
breakCount(241) | 1 |
breakCount(480) | 2 |
Hint
Integer-divide the minutes by 240.
Reference solution in Java
int breakCount(int lengthMinutes) {
if (lengthMinutes < 240) return 0;
return lengthMinutes / 240;
}
