Will this fit in the bay
Goods-in scans a pallet and asks whether the bay it is headed for can take it.
- A missing item, or one with a quantity of zero or less, never fits.
- What is already there plus what is arriving must not exceed capacity.
- Filling the bay exactly is fine.
canStore(item: Item?, onHand: int, capacity: int) → bool
Where you start
function canStore(item: Item | null, onHand: number, capacity: number): boolean {
}Worked examples
| Call | Result |
|---|---|
canStore({"name":"bolt","qty":3}, 0, 100) | true |
canStore({"name":"bolt","qty":5}, 10, 15) | true |
canStore({"name":"bolt","qty":5}, 10, 12) | false |
canStore({"name":"bolt","qty":0}, 0, 100) | false |
Hint
Two guards, then one comparison. Watch the boundary: equal to capacity still fits.
Reference solution in TypeScript
function canStore(item: Item | null, onHand: number, capacity: number): boolean {
if (item === null || item.qty <= 0) return false;
return onHand + item.qty <= capacity;
}
