13. Selection Sort

14. ●Data divided into sorted & unsorted portions ●Smallest values from unsorted portion are selected & put into sorted portion.

15. Bubble Sort

16. ●Compare adjacent elements & swop if out of order ●Largest number ‘bubbles up’ to end of list

17. Bubble Sort ●Compare adjacent elements & swop if out of order ●Largest number ‘bubbles up’ to end of list

18. Quick Sort

19. ●Pick random element ‘pivot’ ●Put to one side ●Compare other elements to ‘pivot’ ●Put smaller to left ●Larger to right ●Repeat with other groups

20. Quick Sort ●Divide & conquer ●Larger lists
