ELI5: Explain Like I'm 5

Priority queue

A priority queue is like lining up for ice cream! The difference is that instead of lining up in order of who got there first, we'll be lining up in order of who gets the ice cream first. The person who has the most important reason for getting the ice cream gets served before those with less important reasons.

So, we'll have a group of people, and each person has a number that tells us how important they are. The person with the highest number is the most important, and they get served first. Let's say we have people with the numbers 5, 2, 8, and 1. The person with number 8 is the most important one, so they'll be served first. Then the person with number 5, followed by the person with number 2, and finally the person with number 1.

That's how a priority queue works! It's a kind of data structure that organizes information based on its priority. The item with the highest priority gets served first in a queue.
