Ask about edge cases before coding. Empty arrays, single elements, all duplicates, negative numbers, integer overflow. Each constraint shapes your solution differently. Ask: "Can the input be empty? How should I handle that?" and "Are all values positive, or can they be negative?" Getting these answers upfront prevents rewriting code later when you discover your solution doesn't handle them. Edge cases cause bugs. Bugs cost interviews. Ask first.
