How does Ruby's case statement behave when using in clauses with range patterns?

AIt only matches exact values, not ranges.
BIt matches the value if it falls within the specified range pattern.
CIt throws an error if ranges are used inside <code>in</code> clauses.
DIt ignores the <code>in</code> clauses and always executes the <code>else</code> block.

    Range patterns match values inside them [OK]
Quick Trick: Ranges in in match values inside them [OK]
Common Mistakes:
MISTAKES
  • Thinking in only matches exact values
  • Assuming ranges cause errors in pattern matching
