Q2. Is time complexity of HashMap always O(1) ?
Ans. 
No, time complexity of HashMap is not always O(1).

• 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.
