ਤੁਸੀਂ ਕਿਸੇ ਸਮੱਸਿਆ ਲਈ ਸਹੀ ਡੇਟਾ ਸਟ੍ਰਕਚਰ ਨੂੰ ਕਿਵੇਂ ਚੁਣਦੇ ਹੋ?

1. How do you access data?  by index -> array
                            by key   -> hash map
                            by order -> tree / heap
2. Need ordering?           sorted   -> balanced BST / sorted array
                            FIFO     -> queue
                            LIFO     -> stack
3. Frequent middle inserts? -> linked list
4. Need fast "seen it?"     -> set / hash map
5. Need "best/min/max next" -> heap (priority queue)
