Exercises / The Auditor
The Auditor
Spot the one wrong number hidden in a receipt, under time pressure.
How it works
A generated receipt of line items, subtotal, and total is shown, sometimes with exactly one deliberately wrong value hidden among them, sometimes with no error at all. You identify where the error is, or report that there is none.
