Welcome to our coding solutions channel! Today, we're diving into a fascinating problem: "1700. Number of Students Unable to Eat Lunch." This scenario unfolds in a school cafeteria, where a delicate balance between sandwich types and student preferences leads to an intriguing challenge. Each student in line has a specific preference for either circular or square sandwiches, represented by 0s and 1s. The cafeteria has prepared an equal number of sandwiches to students, also in the form of circular and square sandwiches, and stacked them up for distribution.

As we unravel this problem, we'll explore how to efficiently determine the number of students unable to eat lunch based on their preferences and the order of sandwiches in the stack. We aim to simulate the lunch distribution process where each student at the front of the queue either gets their preferred sandwich and leaves the queue or moves to the end of it if their preference doesn't match the top sandwich of the stack.

Our solution walks through arrays representing students' preferences and the stack of sandwiches, tracking the count of each sandwich type and matching them with the students' preferences. We'll break down each step of the algorithm, explain the logic behind the operations, and illustrate how we can guarantee that every student who can get their preferred sandwich does so, leaving us with the count of those who can't.

Join us as we code our way through this problem, showcasing a clever solution that balances simplicity and efficiency. Whether you're a beginner eager to learn more about problem-solving in programming or an experienced coder looking for a quick refresher on handling arrays and loops, this video has something for everyone. Let's get started and find out which students will have to miss out on their lunch today!
