How busy was the line
A shift board shows what share of the planned time the line was actually running.
- A whole-number percentage, rounded half up.
- Running longer than planned still reads as 100 — the board does not show more than full.
- No planned time means no percentage: return 0.
utilisationPercent(runMinutes: int, plannedMinutes: int) → int
Go 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
func utilisationPercent(runMinutes int, plannedMinutes int) int {
}
Worked examples
| Call | Result |
|---|---|
utilisationPercent(420, 480) | 88 |
utilisationPercent(480, 480) | 100 |
utilisationPercent(500, 480) | 100 |
utilisationPercent(0, 480) | 0 |
Hint
Round first, then cap. Capping first hides the rounding.
Reference solution in Go
func utilisationPercent(runMinutes int, plannedMinutes int) int {
if plannedMinutes <= 0 || runMinutes <= 0 {
return 0
}
pct := (runMinutes*100 + plannedMinutes/2) / plannedMinutes
if pct > 100 {
return 100
}
return pct
}
