Given a binary tree of integers, your task is to print the right view of it. The right view represents a set of nodes visible when the tree is viewed from the righ...
The task is to print the right view of a binary tree, representing nodes visible from the right side in top-to-bottom order.
Traverse the tree level by level and keep track of the rightmost node at each level
Print the rightmost node of each level to get the right view of the tree
Use a queue for level order traversal and a map to store the rightmost nodes
A thief is planning to rob a store and can carry a maximum weight of 'W' in his knapsack. The store contains 'N' items where the ith item has a weight of 'wi' and a value of...
Yes, the 0/1 Knapsack problem can be solved using dynamic programming with a space complexity of not more than O(W).
Use a 1D array to store the maximum value that can be stolen for each weight from 0 to W.
Iterate through each item and update the array based on whether including the item would increase the total value.
The final value in the array at index W will be the maximum value that can be stolen.

You can find the size of an array in C or C++ by dividing the total size of the array by the size of one element.
Calculate the total size of the array by multiplying the number of elements by the size of each element.
Divide the total size by the size of one element to get the size of the array.
For example, if you have an array of strings arr[] = {'hello', 'world', 'example'}, you can find the size by dividing the total...
B+ trees are used for indexing in databases to efficiently search and retrieve data.
B+ trees are balanced trees where each node can have multiple keys and child pointers.
Data is stored in leaf nodes, while non-leaf nodes are used for navigation.
B+ trees are commonly used in databases because of their ability to efficiently search and retrieve data.
Example: In a database table with an index on a specific column, B+ tree...

You are given an n-ary tree consisting of 'N' nodes. Your task is to determine the maximum sum of the path from the root to any leaf node.

Find the maximum sum of the path from the root to any leaf node in an n-ary tree.
Traverse the tree from root to leaf nodes while keeping track of the sum of each path.
At each node, calculate the sum of the path from the root to that node and update the maximum sum found so far.
Consider using depth-first search (DFS) or breadth-first search (BFS) for tree traversal.
Handle cases where nodes have negative values or where ...

An interface in Java is a reference type that defines a contract for classes to implement methods without providing their implementation.
Interfaces can contain method signatures and constants but no method bodies.
A class implements an interface using the 'implements' keyword. Example: 'class MyClass implements MyInterface'.
Multiple interfaces can be implemented by a single class, allowing for multiple inheritance of ty...
OOP in Java is a programming paradigm based on objects, enabling code reusability, encapsulation, inheritance, and polymorphism.
Encapsulation: Bundling data and methods that operate on the data within one unit (class). Example: private variables with public getters/setters.
Inheritance: Mechanism where one class inherits properties and behavior from another. Example: class Dog extends Animal.
Polymorphism: Ability to pre...
