Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
This bug belongs to the infinite loops pattern
The tab freezes, nothing prints, and the loop condition never becomes false.
What went wrong: i is never increased, so the loop looks at arr[0] again and again, forever.
The fix: add i++; at the end of the loop, or use for (const value of arr) which moves along by itself.
Remember: in a while loop, you must move the index yourself.
The pattern behind it: infinite loops.
