Reverse the first k elements in the queue is a common problem in data structures and algorithms. A queue is a data structure that follows the FIFO (First In First Out) principle. In a queue, elements are inserted from one end called the "rear" and removed from the other end called the "front". So, reversing the first K elements of a queue means that we need to dequeue the first K elements from the front of the queue, reverse them, and then enqueue them back to the front of the queue.<\/p>\n

Reversing First K Elements Queue<\/h2>\n

Given a queue, we have to reverse the first k elements which are present in it.<\/p>\n

What is Queue?<\/h2>\n

Linear data structures include queues. First in, First out, or FIFO, applies to the queue. The element that goes in first is the element that comes out first, in other words.<\/p>\n

For Example: A ticket Queue outside a cinema hall where the person enters the queue first will get the ticket first.<\/p>\n
