How can I print out files recursively like the example(Individual files first, and then subdirectories and files inside subdirectories) by entering a specified Path?

And the resulting output: /home/algol/ics32/lectures/README /home/algol/ics32/lectures/schedule.txt /home/algol/ics32/lectures/References.txt /home/algol/ics32/lectures/l1 /home/algol/ics32/lectures/l1/lecture1.ppt /home/algol/ics32/lectures/11/lecture1.pdf /home/algol/ics32/lectures/l1/logos /home/algol/ics32/lectures/l1/logos/uci.jpg /home/algol/ics32/lectures/11/logosasa.jpg /home/algol/ics32/lectures/12 /home/algol/ics32/lectures/12/lecture2.ppt /home/algol/ics32/lectures/12/lecture2.pdf /home/algol/ics32/lectures/13 /home/algol/ics32/lectures/13/lecture3.ppt /home/algol/ics32/lectures/13/lecture3.pdf
