Solutions

1. Increase the (min, max) range or reduce count so the number of unique integers requested fits in the range.

When it happens

Trigger: generateUniqueInt cannot produce the requested count of unique integers within the given min/max range.

Common situations: Same as narrow-range overflow; widen the range or reduce count.
