Sorting A Queue C++ (Data structures)

The queue is basically a FIFO (First In First Out).

Sorting:

Sorting works on many algorithms. The sorting algorithm is a comparison-based algorithm in which each pair of adjacent elements is compared and the elements are swapped if they are not in the order.

How sorting will work:

Here is an example which is explaining the concept of sorting a Queue.

Queue:

19 39 29 40 50
Front Rear

Start from the first two numbers, compare both of them to check which one is greater.

Here 39 is already greater than 19 so it is already sorted.

19 39 29 40 5
Smaller Greater

 

 

No Swapping needed.

Now we will compare 39 and 29

19 39 29 40 5
  Greater Smaller

Now compare 39 and 5. 39 and 5 will be swapped here.

19 29 39 5 40
  Greater Smaller

 

 

The queue will be:

29 and 5 will be compared, these will be swapped because 5 is less than 29.

19 29 5 39 40
  Greater Smaller
