The grid passed in is just a multidimensional array (2-D array) where each slot in the inner array is an object with property weight. ![]() Id really love it if you could take a look and tell me how to improve my code. The following picture illustrates a queue:Īnother important operation of a queue is getting the element at the front called peek. I just implemented a version of A search in JavaScript for educational purposes. The class includes methods like enqueue(), dequeue(), peek(), isEmpty(), size(). Remove an element from the front of the queue, which is called dequeue. The Queue class is created to implement the queue data structure.Insert a new element at the end of the queue, which is called enqueue.Introduction to the Queue data structureĪ queue is an ordered list of elements where an element is inserted at the end of the queue and is removed from the front of the queue.Ī queue works based on the first-in, first-out (FIFO) principle, which is different from a stack, which works based on the last-in, first-out (LIFO) principle.
