let queue = new Queue();
queue.enqueue(10);
queue.enqueue(20);
queue.enqueue(30);
console.log(queue.printQueue()); // Output: 10 20 30
queue.dequeue();
console.log(queue.printQueue()); // Output: 20 30

Searching algorithms are used to find an element in a data structure. One common algorithm is binary search, which works on sorted arrays.
