Calculate remaining minutes
Difficulty: Easy
Return available minus used. Both inputs are nonnegative integers; a negative answer represents using more than available.
The function wrapper is supplied. Replace the expression after return; the runner calls solve. Comments beginning with // do not run.
Examples
20, 5150, 004, 9-5Constraints
Use only supplied arguments and preserve inputs. Unless stated otherwise, numbers have magnitude <= 10000 and arrays/strings contain <= 100 elements/code units. For products, intermediate and final magnitudes stay below 2^53. Return the stated JSON-compatible value. No DOM, files, timers, fetch, network or packages.
