Q1. Implement Hash Maps
Ans. 
Hash maps are data structures that store key-value pairs and provide efficient lookup, insertion, and deletion operations.
• Hash maps use a hash function to convert keys into array indices.

• Collisions can occur when multiple keys hash to the same index, requiring collision resolution techniques.

• Common collision resolution methods include chaining and open addressing.

• Hash maps have an average time complexity of O(1) for ba...read more

Q1. How does python handle multiple object types ??
Ans. 
Python uses dynamic typing to handle multiple object types, allowing variables to change types during runtime.
• Python uses dynamic typing, meaning variables can hold different types of objects at different times.

• Python does not require explicit declaration of variable types, allowing for flexibility in handling multiple object types.

• Python supports polymorphism, allowing objects of different types to be treated as insta...read more

Q2. What happens when I cast a python variable ??
Ans. 
When you cast a Python variable, you are converting its data type to a different type.
• Casting is the process of changing a variable's data type.

• For example, casting a string to an integer: x = '10' -> int(x) = 10

• Casting can result in data loss if the conversion is not possible or accurate.
