What are the methods for sorting queues in C++?

There are several methods for sorting queues in C++.

1. Insertion sort: Take out elements one by one from the original queue and insert them into the new queue in the correct order. This maintains the order of the queue until all elements have been placed in the new queue.
2. Bubble sort: Repeatedly compare adjacent elements and swap them if they are in the wrong order. This will bubble the largest element to the end of the queue with each round of iteration.
3. Quick sort: Choose an element in the array as a pivot, then put elements smaller than the pivot to the left, and elements larger than the pivot to the right. Then recursively quick sort the two sub-arrays on the left and right.
4. Merge sort involves splitting the queue into two sub-sequences, sorting each one separately, and then merging the two sorted sub-sequences into one. This process gradually breaks down the queue into smaller parts until each part consists of only one element.
5. Heap sort: Arrange the elements in the queue into a maximum (or minimum) heap, then swap the top element with the last one and remove the last element from the heap. Repeat this process until the heap is empty.

The above are several common C++ queue sorting methods, each with its own advantages and disadvantages. Choosing the appropriate method depends on the specific requirements and data size.
