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.

The task is to distribute candies to students based on their performance while minimizing the total candies distributed.
Create an array to store the minimum candies required for each student.
Iterate through the students' ratings array to determine the minimum candies needed based on the adjacent ratings.
Consider both left-to-right and right-to-left passes to ensure fair distribution.
Keep track of the total candies dist

Implement Merge Sort algorithm to sort a sequence of numbers in non-descending order.
Use Divide and Conquer approach to recursively divide the input array into two halves.
Merge the sorted halves to produce a completely sorted array.
Ensure the implementation handles the constraints specified in the problem statement.
Example: For input [3, 1, 4, 1, 5], the output should be [1, 1, 3, 4, 5].
Tip 1 : Practice Atleast 250 Questions
Tip 2 : Do atleast 2 projects
Tip 1 : Do not put false things on resume.
