Check If One Array is a Subset of Another in C++ | Simple and Efficient Solution

In this C++ program, we demonstrate how to check if one array is a subset of another using an unordered set for optimal performance. This method ensures a time-efficient solution with constant time complexity for lookups. Whether you're working with small or large arrays, this approach will help you solve the subset problem efficiently.
