The code takes the numbers: 44 33 ... and so on
and runs a function called process in the background (creates a separate child process) ; the trailing & does this.
All the child does is to sleep for the number of seconds, then it wakes up and displays the number of seconds it slept.
The parent waits at the end for all children to wake up and print.
Since 45 is the largest time in seconds, the total time it takes the whole script to run will be very close to 45 seconds.
I think the script is meant as a shell script teaching example. You should see the numbers appear in numeric sequence.

Thanks for the information, so if i wanted to Adjust the script to output each value on a line by itself and reverse the order of processing, how might I do it?
I do not get what you mean. You can enter any small group positive numbers in any order and they will appear in numeric order. You will need another completely different algorithm to print them in reverse order. sort comes to mind:
[whole script]
So, this is probably not what you want. Please provide example input, with example output.

I'm using Cygwin bash on Windows 10.
