Q1. Explain about Exception Handling and how many types of Exceptions and we can handle Exception
Exception handling is a mechanism to handle runtime errors and prevent program crashes.
There are two types of exceptions: checked and unchecked.
Checked exceptions are checked at compile-time and must be handled or declared.
Unchecked exceptions are runtime exceptions and do not need to be handled or declared.
We can handle exceptions using try-catch blocks.
We can also use finally block to execute code regardless of whether an exception is thrown or not.
Q2. Make a copy of binary tree with additional friend node that links to a random node
Copy a binary tree with a friend node linking to a random node.
Create a new node for each node in the original tree
Copy the value of the original node to the new node
Link the new node to the corresponding node in the new tree
Generate a random number to select a random node in the new tree
Link the friend node of each node in the new tree to the randomly selected node

Q3. Find the number of areas (an area is a group of connected 1s) in a given 0/1 matrix.
Count the number of connected 1s in a 0/1 matrix.
Traverse the matrix and for each 1 encountered, perform a depth-first search to find all connected 1s.
Mark the visited 1s to avoid revisiting them.
Increment the count of areas for each new group of connected 1s found.
Return the total count of areas.
Consider edge cases like empty matrix, matrix with all 0s, or matrix with all 1s.
Q4. React component with states and props uses
React components can have states and props to manage data and communication between components.
States are used to manage data that can change over time within a component.
Props are used to pass data from parent components to child components.
States are mutable and can be changed using setState() method.
Props are read-only and cannot be changed by the child component.
Example:
where 'name' is a prop passed to MyComponent.

Q7. what is an LCR circuit?
An LCR circuit is a circuit that contains inductors (L), capacitors (C), and resistors (R) connected in series or parallel.
An LCR circuit can exhibit resonance at a certain frequency where the impedance is minimized.
The behavior of an LCR circuit can be described using complex numbers and phasors.
Examples of LCR circuits include band-pass filters, oscillators, and impedance matching networks.
Q8. Find prime number in Javascript
Use a loop to check if a number is divisible by any number other than 1 and itself.
Iterate through numbers from 2 to n-1
Check if n is divisible by any number in the range
If not divisible, n is a prime number
