Q1. Explain OOPS concept
Ans. 
OOPS (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
• OOPS focuses on creating objects that interact with each other to solve complex problems

• Key principles include encapsulation, inheritance, polymorphism, and abstraction

• Encapsulation ensures that the internal state of an object is hidden from the outside world

• Inheritance allows a class to inherit...read more

Q1. How make a queue using a stack
Ans. 
To implement a queue using a stack, use two stacks and simulate the queue operations.
• Use two stacks, one for enqueue operation and one for dequeue operation.

• For dequeue operation, if the dequeue stack is empty, pop all elements from enqueue stack and push onto dequeue stack.

• Then pop from the dequeue stack to simulate dequeue operation.

Ans. 
Count the number of subarrays in an array whose XOR is equal to a given value.
• Iterate through the array and keep track of XOR values and their frequencies using a hashmap.

• For each element in the array, calculate the XOR value with all previous elements and check if it equals the given XOR value.

• Use the concept of XOR to efficiently solve the problem.

• Handle edge cases like XOR value being 0 separately.

• Time complexity ca...read more
