For example, in any airline, baggage under the \u201cFirst-Class\u201d or \u201cBusiness\u201d arrives before other baggage.\nA priority Queue is a type of queue that follows the given below properties:<\/p>\n<ul>\n<li>An item with higher priority will be dequeued before the item with lower priority.<\/li>\n<li>If two elements present in the priority queue are having the same priority, then they will be served according to the order in which they are present in the queue.<\/li>\n<\/ul>\n<p>The priority queue is widely used in many applications like job scheduling algorithms, CPU and Disk scheduling, and managing various resources shared between different processes, etc.<\/p>\n<h3>How is the Priority Value assigned in the Priority Queue?<\/h3>\n<p>Usually, an element&#8217;s value is considered for assigning the priority. For example, the element with bigger value will have a higher priority than the element with lower value.\nWe can also set priorities according to our demand.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/prepbytes-misc-images.s3.ap-south-1.amazonaws.com\/assets\/1657692465379-Image-02.png\" alt=\"\" \/><\/p>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-center\" data-align=\"center\"><strong>S.no<\/strong><\/th><th><strong>Circular Queue<\/strong><\/th><th><strong>Priority Queue<\/strong><\/th><\/tr><\/thead><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\">1.<\/td><td>As the name suggests, a circular<br>queue is circular in storing the <br>elements in it.<\/td><td>In the priority queue, elements <br>are inserted and deleted on the <br>basis of their priority.<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">2.<\/td><td>Also known as a ring buffer.<\/td><td>Also known as a simple queue.<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">3.<\/td><td>Elements can be enqueued or <br>dequeued from the queue in <br>O(1) time.<\/td><td>Three main operations are <br>insert, delete and display.<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">4.<\/td><td>Both the front and rear pointer <br>wrap around to the beginning <br>of the array.<\/td><td>It does not allow elements in <br>sorted array.<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">5.<\/td><td>It conquers the problem of linear queue.<\/td><td>It allows duplicate elements.<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">6.<\/td><td>Less memory is required.<\/td><td>More Memory is required.<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">7.<\/td><td>More efficient.<\/td><td>Less Efficient.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p>This article tried to discuss the <strong>Difference between Circular Queue and Priority Queue<\/strong>.
