- Q1. AVL tree balance checking
- Q2. Median of 2 sorted arrays in O(log N) time complexity and O(1) space complexity
- Ans.
Find median of 2 sorted arrays in O(log N) time complexity and O(1) space complexity
Use binary search to find the partition point in both arrays
Calculate the median based on the partition point and array sizes
Adjust the partition points based on the median value
Repeat until the partition points are at the median
Handle edge cases such as empty arrays and uneven array sizes
- Q3. Strings Anagram in O(1) space complexity
- Ans.
Anagram of strings in O(1) space complexity
Use a fixed size array of integers to store the frequency of characters in the first string
Iterate through the second string and decrement the frequency of each character in the array
If all the frequencies are zero, then the strings are anagrams
Return true or false accordingly
- Q4. Level order traversal of a tree using Queue
- Ans.
Level order traversal of a tree using Queue
Create a queue and add the root node to it
While the queue is not empty, remove the front node and print its value
Add the left and right child nodes of the removed node to the queue
Repeat until the queue is empty
- Q5. Reverse level order traversal of a tree using Queue
- Ans.
Reverse level order traversal of a tree using Queue
Create a queue and push the root node into it

Add the popped node to a stack
Once the queue is empty, pop elements from the stack and print them
- Q6. BFS and DFS Difference
- Ans.
BFS and DFS are graph traversal algorithms. BFS explores nodes level by level while DFS explores nodes depth by depth.
BFS uses a queue while DFS uses a stack or recursion.
BFS is optimal for finding shortest path while DFS is optimal for finding a path between two nodes.
BFS requires more memory as it stores all the nodes at each level while DFS requires less memory.
BFS can be used to find connected components while DFS

- Ans.
Recursively delete a tree by deleting all its child nodes and then the parent node.

Then move up to the parent nodes and delete them.
Repeat until the root node is deleted.
Use post-order traversal to ensure child nodes are deleted before parent nodes.
- Q14. Recursively deleting from end
- Ans.
Recursively delete elements from the end of an array.

- Q1. How do you dynamically allocate a 2D array in C?
- Ans.
Use double pointer to dynamically allocate memory for array of strings in C.
Declare a double pointer to hold the 2D array of strings.
Allocate memory for the rows first using malloc.
Then allocate memory for each string in the row using malloc.
Assign values to the strings in the array.
Example: char **array = malloc(rows * sizeof(char *));
Example: array[i] = malloc(strlen(str) + 1); strcpy(array[i], str);
- Q2. What are virtual functions in C++?
- Ans.
Virtual functions in C++ are functions that can be overridden in derived classes, allowing for polymorphic behavior.
Virtual functions are declared using the 'virtual' keyword in the base class.
They are used to achieve runtime polymorphism in C++.
Derived classes can override the virtual functions defined in the base class.
Example: class Base { public: virtual void display() { cout << 'Base class dis...
- Q3. What are virtual base classes?
- Ans.
Virtual base classes are classes that are inherited virtually to avoid multiple instances of the same base class in a derived class hierarchy.
Virtual base classes are used in multiple inheritance to prevent the Diamond Problem.

Technical interview round with questions based on OS/Networking etc.
- Q1. What is the system call that creates a separate connection?
- Ans.
The system call that creates a separate connection is fork()
fork() is a system call in Unix-like operating systems that creates a new process by duplicating the existing process
The new process created by fork() is called the child process, while the original process is called the parent process
fork() is commonly used in network programming to create separate connections for handling multiple clients

Passive close: Server initiates the connection release process by sending a FIN packet.
Simultaneous close: Both client and server send FIN packets to each other simultaneously.
Abortive close: Connection is terminated abru...
- Q3. What protocols are used by the MAC layer?

CSMA/CD (Carrier Sense Multiple Access with Collision Detection) is used in wired networks to detect and handle collisions.
TDMA (Time Division Multiple Access) is used in networks where devices are assigned specific
- Q4. What is the ARP protocol?
- Ans.
ARP (Address Resolution Protocol) is a protocol used to map an IP address to a MAC address in a local network.
ARP is used to resolve IP addresses to MAC addresses in a local network.
It operates at the data link layer of the OSI model.
ARP requests are broadcasted to all devices on the network.
Example: When a device wants to communicate with another device on the same network, it uses ARP to find the MAC address correspo
