Normalization is the process of organizing data in a database to eliminate redundancy and improve data integrity.
Normalization helps in reducing data redundancy by breaking down a large table into smaller, more manageable tables.
It ensures that each piece of data is stored only once, reducing storage space and improving efficiency.
Normalization also helps in maintaining data integrity by preventing anomalies like updat...
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 is a fundamental concept in object-oriented programming.
It allows a single interface to be used for different types of objects.
Polymorphism can be achieved through method overriding and method overloading.
Example: A shape class with different subclasses like circle, square,

You are given an integer array 'ARR' of size 'N' and an integer 'S'. Your task is to find and return a list of all pairs of elements where each sum of a pair equals 'S'.
Given an array and a target sum, find pairs of elements that add up to the target sum.
Iterate through the array and for each element, check if the complement (target sum - current element) exists in a hash set.
If the complement exists, add the pair to the result list. Otherwise, add the current element to the hash set.
Sort the pairs based on the first element and then the second element to meet the required output form

Pointers in C/C++ are variables that store memory addresses. They are used to manipulate memory directly and improve performance.
Pointers are declared using an asterisk (*) before the variable name.
Pointers can be used to dynamically allocate memory using functions like malloc() and free().
Pointers can be used to pass variables by reference to functions.
