Hashing is a technique used to map data to a fixed-size array, collision occurs when two different inputs produce the same hash value.
Hashing involves using a hash function to map data to a fixed-size array.
Collision happens when two different inputs produce the same hash value.
Common techniques to handle collisions include chaining and open addressing.
No, time complexity of HashMap is not always O(1).
Time complexity of HashMap is O(1) on average, but can degrade to O(n) in worst case scenarios.
Worst case scenarios include hash collisions, which can lead to linear probing and degrade performance.
Load factor and capacity of the HashMap can also affect time complexity.
In scenarios where many keys hash to the same index, the time complexity can degrade.
Common coding problems difficulty laver moderate
