- Q1. Implement queue with the help of two stacks
- Ans.
Queue can be implemented using two stacks by maintaining the order of elements in the stacks.
Create two stacks, let's call them stack1 and stack2
When an element is enqueued, push it to stack1
When an element is dequeued, pop all elements from stack1 and push them to stack2
Pop the top element from stack2 and return it as the dequeued element
If stack2 is empty, repeat step 3
To get the front element of the queue, peek the

- Ans.
Check if a number is a power of 2 or not.
A power of 2 has only one bit set in its binary representation.
Use bitwise AND operator to check if the number is a power of 2.
If n is a power of 2, then n & (n-1) will be 0.

- Q1. What is event bubbling?
- Ans.
Event bubbling is the propagation of an event from the innermost child element to the outermost parent element.

Can be stopped using event.stopPropagation()
Can be useful for event delegation

The .on() method can also handle dynamically added elements
The .click() method cannot handle dynamically added elements
