Find the subset of an array with the largest sum of continuous positive numbers.
Iterate through the array and keep track of the current sum and the maximum sum seen so far.

- Q1. Design a minimum stack that supports the following operations: push, pop, top, and retrieving the minimum element in constant time.
- Ans.
Design a stack that supports push, pop, top, and retrieving minimum element in constant time.
Use two stacks - one to store the actual elements and another to store the minimum values encountered so far
When pushing an element, check if it is smaller than the current minimum and if so, push it to the minimum stack
When popping an element, check if it is the current minimum and if so, pop from the minimum stack as well

- Q1. Smallest window in a string containing all the characters of another string.(GFG)
- Ans.
Find the smallest window in a string containing all characters of another string.
Use a sliding window approach to find the smallest window
Create a frequency map of characters in the second string
Slide the window and update the frequency map until all characters are found
Track the minimum window size and indices
- Q2. Check whether linked list is Pallindrome or not
- Ans.
To check if a linked list is a palindrome, compare the first half of the list with the reversed second half.
Traverse the linked list to find the middle element using slow and fast pointers.
Reverse the second half of the linked list.
Compare the first half with the reversed second half to check for palindrome.
- Q3. Deadlocks,4 conditions of Deadlocks and ways of preventing Deadlock
- Ans.
Deadlocks occur when two or more processes are waiting for each other to release resources, leading to a standstill.
4 conditions of Deadlocks: mutual exclusion, hold and wait, no preemption, circular wait
Preventing Deadlocks: using a proper resource allocation strategy, implementing timeouts, avoiding circular wait, using deadlock detection and recovery algorithms
Example: Two processes each holding a resource and waiti...

- Q1. Algorithm to find if any 5 numbers add up to the value of the Sum
- Ans.
Use a hash set to store seen numbers and check if the complement of current number is in the set.
Iterate through the array and for each number, check if the complement of the current number is in the hash set.
If the complement is found, return true. Otherwise, add the current number to the hash set.
Repeat this process for all numbers in the array.
Example: Array [1, 2, 3, 4, 5] and Sum 9 should return true as 4 + 5 = 9.
- Q2. What is DNS(Domain Name System)
- Ans.
DNS is a system that translates domain names to IP addresses, allowing users to access websites using human-readable names.
DNS is like a phone book for the internet, translating domain names (e.g. google.com) to IP addresses (e.g. 172.217.3.206).
DNS servers store records that map domain names to IP addresses, helping users navigate the internet.
DNS also helps with email delivery by translating domain names in email add

‘Arcade’ is a very famous mall in Berland. It has a very ...
- Ans.
It can be solved by using mathematics. If the height of wall is less than or equal to x, only one jump is required. Otherwise run a while loop while height is greater than x, and calculate the jumps required by updating the height to height of wall – (climb up-climb down).
- Q2. Smallest Window
You are given two strings S and X containing random characters. Your task is to find the smallest substring in S which contains all the characters present in X.
Example:
Let S = “abdd” ... - Ans.
The naïve approach is to generate all substrings of string1 and for each substring, check whether the substring contains all characters of string2. Finally, print the smallest substring containing all characters of string2.
The efficient solution is to use hashing. First check if the length of the string is less than the length of the given pattern, if yes then no such window can exist . Next, store the occurrence of ch... - Q3. Rat In A Maze

2. If the move is possible, then move to that cell while storing the character corresponding to the move(D,L,R,U) and again start looking for the valid move until the last cell [n-1,n-1] is reached.
3. Along with it, keep on marking the cells as visited and when all the ...

Questions based on OOPS were asked in this round.
- Q1. OOPS Question
What is a virtual function?
- Ans.
A C++ virtual function is a member function in the base class that you redefine in a derived class. It is declared using the virtual keyword. It is used to tell the compiler to perform dynamic linkage or late binding on the function. A 'virtual' is a keyword preceding the normal declaration of a function. When the function is made virtual, C++ determines which function is to be invoked at the runtime based on the type
- Q2. OOPS Question
What are the types of polymorphism?
- Ans.
Polymorphism is of two types :
1. Compile Time Polymorphism :
Invokes the overloaded functions by matching the number and type of arguments. The information is present during compile-time. This means the C++ compiler will select the right function at compile time. It is achieved through function overloading and operator overloading.
2. Run Time Polymorphism :
This happens when an object’s method is called durin... - Q3. OOPS Question
Difference between deep copy and shallow copy
- Ans.
A shallow copy of a collection is a copy of the collection structure, not the elements. With a shallow copy, two collections now share the individual elements.
Deep copies duplicate everything. A deep copy of a collection is two collections with all of the elements in the original collection duplicated.
