Find the maximum sum of any contiguous subarray within an array in O(N) time complexity.
Use Kadane's algorithm to find the maximum sum subarray in O(N) time complexity
Initialize two variables: max_sum and current_sum to keep track of the maximum sum subarray
Iterate through the array and update current_sum by adding the current element or starting a new subarray
Update max_sum if current_sum is greater than max_sum
Return...

Interview of DSA + OOPS + Databse(SQL query) + Operating System
Given a binary tree, your task is to print the left view of the tree. The left view of a binary tree contains the nodes visible when the tree is viewed from the left side.
The task is to print the left view of a binary tree, which contains the nodes visible when the tree is viewed from the left side.
Traverse the tree in a level order manner and keep track of the leftmost node at each level.
Use a queue to perform level order traversal.
Print the leftmost node at each level to get the left view of the binary tree.
CHAR is fixed length while VARCHAR2 is variable length in SQL.
CHAR stores fixed length strings, padding with spaces if necessary.
VARCHAR2 stores variable length strings, not padding with spaces.
CHAR is faster for fixed length data, VARCHAR2 is more flexible for varying length data.
There are three types of constructors in C++: default constructor, parameterized constructor, and copy constructor.
Default constructor: Constructor with no parameters.
Parameterized constructor: Constructor with parameters.
Copy constructor: Constructor that initializes an object using another object of the same class.
Example: // Default constructor ClassName() {} // Parameterized constructor ClassName(int x, int y) :...
Overloading is having multiple methods in the same class with the same name but different parameters, while overriding is implementing a method in a subclass that is already defined in the superclass.
Overloading involves multiple methods with the same name but different parameters.
Overriding involves implementing a method in a subclass that is already defined in the superclass.
Overloading is resolved at compile time ba...

We were supposed to give test in any time between 3 PM to 9 PM.
You are located at point ‘A’, the top-left corner of an M x N matrix, and your target is point ‘B’, the bottom-right corner of the same matrix. Your task is to calcula...
The problem involves finding the total number of unique paths from the top-left to bottom-right cell of a matrix by moving only right or down.
Use dynamic programming to solve the problem efficiently.
Create a 2D array to store the number of unique paths at each cell.
Initialize the first row and first column with 1 as there is only one way to reach them.
For each cell (i, j), the number of unique paths is the sum of paths...
We are provided with a tree containing 'N' nodes, numbered from 0 to N-1. The objective is to determine the total number of nodes within each subtree of the provided tree. Speci...
Given a tree with N nodes, find the number of elements in each subtree rooted at every node.
Traverse the tree using Depth First Search (DFS) to calculate subtree sizes for each node.
Use an array to store subtree sizes for each node, starting with leaf nodes having size 1.
The subtree size of a node is the sum of subtree sizes of its children plus 1 for the node itself.

Pair Programming Interview( this round is similar to machine coding round) it started around 11 AM
Focus Areas: Problem solving and implementation of extensions.
The pair coding round is focused on OOPS concepts. You are paired with a TWer for this round. They let you code first for an hour and in the next hour they review your code and suggest changes which would improve the code structure, readability and make it modular and reusable and functional.
Ninja stands at the start of a wooden bridge over a river. Some segments of the bridge are damaged. The undamaged segments, marked as 'safe', are listed in an array S...
Check if Ninja can cross the river by jumping from one safe segment to another based on given constraints.
Iterate through the 'SAFE' array and check if Ninja can make the required jumps to reach the last safe segment.
Ensure that the next jump is either 'X' - 1, 'X', or 'X' + 1 units from the previous jump.
Return 'true' if Ninja can successfully cross the river, otherwise return 'false'.

Students who were shortlisted from Pair Programming round was selected for this round around 3 PM. In this round there were two interviewer.
You are given the head node of a singly linked list. Your task is to return a pointer pointing to the middle of the linked list.
If there is an odd number of elements, return the ...
Return the middle element of a singly linked list, or the one farther from the head if there are even elements.
Traverse the linked list with two pointers, one moving twice as fast as the other
When the fast pointer reaches the end, the slow pointer will be at the middle
Return the element pointed to by the slow pointer
Tip 1 : Have good grasp on OOPS since they have a round named Pair Programming round which is focused upon this.
Tip 2 : Write clean, modular and functional code.
Tip 3 : Practice Data Structures and Algorithms
Tip 4 : You should know breadth and depth of whatever is mentioned in your resume.
Tip 5 : Be loud and clear.
Tip 1 : Make single page resume.
Tip 2 : Mention relevant things on resume.
Tip 3 : Do not put any false things on resume. Projects, internships you are mentioning be ready to answer questions related to it regarding what you solved, idea, databases, design.
Tip 4 : Contribute in open source, participate in hackathons.
