Say a duration the way a person would
A ticket screen shows how long something took, and "90m" reads worse than "1h 30m".
- Hours and minutes, separated by a single space: 90 becomes "1h 30m".
- Drop the part that is zero: 120 is "2h", 45 is "45m".
- Zero, or anything negative, is "0m".
minutesToText(minutes: int) → string
Where you start
function minutesToText(minutes: number): string {
}Worked examples
| Call | Result |
|---|---|
minutesToText(90) | "1h 30m" |
minutesToText(120) | "2h" |
minutesToText(45) | "45m" |
minutesToText(0) | "0m" |
Hint
Work out both parts, then decide which ones to print.
Reference solution in TypeScript
function minutesToText(minutes: number): string {
if (minutes <= 0) return '0m';
const h = Math.floor(minutes / 60);
const m = minutes % 60;
if (h === 0) return m + 'm';
if (m === 0) return h + 'h';
return h + 'h ' + m + 'm';
}
