Q1. 
Pair Sum Problem Statement
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'.
Note:

Ans. 
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

Q1. Can you provide an example of how to use pointers in C/C++ and discuss different concepts related to them?
Ans. 
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.

Q1. 
Count Subarrays with Given XOR Problem Statement
You are given an array of integers ARR and an integer X. Your task is to determine the number of subarrays of ARR whose bitwise XOR is equal to X.
Example...read more
Ans. 
Count the number of subarrays in an array whose XOR is equal to a given value.
• Iterate through the array and keep track of XOR values and their frequencies using a hashmap.

• For each element in the array, calculate the XOR value with all previous elements and check if it equals the given XOR value.

• Use the concept of XOR to efficiently solve the problem.

• Handle edge cases like XOR value being 0 separately.

• Time complexity ca...read more
