- Compares first 2 numbers in array. Will swap them if the number on the left is greater than the number on the right.
- Goes onto the next 2 numbers, does the same for the rest. Compare, check if larger and switch if needed.
- Now we know that the final number in the array is the largest.
- We repeat the process all again, slowly confirming that we have the largest number after swapping and reaching the end of the array.
