Bug Hunt

Every snippet has one buggy line. Read what it should do, then tap the line that breaks it before the clock runs out.

Quick tips

Run the example. Mentally run the example from the goal through each line. The bug is where the value goes wrong.
Check the boundaries. <= vs <, range(n) vs range(1, n + 1): limits are where most bugs hide.
Watch the types. Form input is text: "20" + 5 is "205" in JavaScript.
Async needs await. A fetch without await gives a Promise, not a response.
Spot copy-paste. Two similar lines where one variable didn't get renamed is a classic.
