💡 COMMON QUESTION VARIATIONS

Understanding common twists helps you adapt during interviews:

Original	Common Variations
Valid Palindrome II	• Allow k deletions • Return indices to remove • Return minimum deletions needed
Shortest Path Binary Matrix	• Return actual path (not just length) • 8 directions vs 4 directions • Multiple start/end points
Basic Calculator	• Only +/- operators • Only +/* operators • Add parentheses support
Clone Graph	• Very large graphs (discuss stack overflow) • Directed vs undirected • Weighted edges
Dot Product Sparse Vectors	• Streaming input • Extremely large arrays • Multiple queries optimization
Insert Circular List	• Given arbitrary pointer (not head) • Multiple insertions • Delete operations
Robot Room Cleaner	• Find specific target • Can move diagonally • Return to start
Merge K Lists	• Return kth element only • Merge first k elements only • Infinite streams
Valid Number	• No exponents (simplified) • Different valid formats • Additional constraints
Simplify Path	• Windows-style paths • Symbolic links • Permission checks
