. Your task is to reverse the string word by word. The input may contain multiple spaces between words and may have leading o...
Reverse words in a string while handling leading, trailing, and multiple spaces.
Split the input string by spaces to get individual words
Reverse the order of the words
Join the reversed words with a single space in between
Handle leading, trailing, and multiple spaces appropriately
You are given a stack of integers. Your task is to reverse the stack using recursion without using any extra space other than the internal stack space used due to recursion...
Reverse a stack using recursion without using any extra space other than the internal stack space.
Use recursion to pop all elements from the original stack and store them in function call stack.
Once the stack is empty, push the elements back in reverse order.
Base case of recursion should be when the original stack is empty.

Convert a binary tree to its mirror tree by interchanging left and right children of all non-leaf nodes.
Traverse the binary tree in a recursive manner.
Swap the left and right children of each non-leaf node.
Continue this process until all nodes have been processed.
You are given a singly linked list with 'N' nodes, each containing integer data, and an integer 'K'. Your goal is to remove the 'K'th node counting from the end of ...
Remove the Kth node from the end of a singly linked list.
Use two pointers approach to find the Kth node from the end.
Handle edge cases like removing the head node or removing the last node.
Update the pointers to remove the Kth node and reconnect the list.

Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Inheritance allows for code reuse and promotes modularity.
The class that is being inherited from is called the superclass or base class.
The class that inherits from the superclass is called the subclass or derived class.
The subclass can access the public and protected members of the superclass.
Inhe...
Regular expressions in PHP are powerful tools for pattern matching and manipulating strings.
Regular expressions are defined using the preg_match() function in PHP.
They are used to search, replace, and validate strings based on specific patterns.
Regex patterns consist of a combination of characters and special symbols.
Modifiers can be added to the pattern to control the matching behavior.
Common regex functions in PHP in...
Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.
Polymorphism allows a single interface to be used for different types of objects.
It enables code reusability and flexibility in object-oriented programming.
For example, a parent class 'Animal' can have multiple child classes like 'Dog', 'Cat', and 'Bird'. They can all be treated as 'Anim...
