Try to write an algorithm to implement quick sort.

Sure, here is a simple algorithm to implement Quick Sort:
1. Choose a pivot element, which can be any element from the array.
2. Partition the array around the pivot element, such that all the elements to the left of the pivot are smaller than the pivot element, and all the elements to the right of the pivot are greater than or equal to the pivot element.
3. Recursively apply this process to the sub-arrays to the left and right of the pivot until the entire array is sorted.
Here is the step-by-step implementation of the algorithm in pseudocode:
```
function quicksort(array)
if length(array) <= 1
return array
else
pivot = choose_pivot(array)
left = []
right = []
for element in array
if element < pivot
append element to left
else if element >= pivot
append element to right
sorted_left = quicksort(left)
sorted_right = quicksort(right)
return concatenate(sorted_left, [pivot], sorted_right)
```
In this implementation, the `choose_pivot` function can be any function to select a pivot element. A common approach is to select the first or last element of the array as the pivot, or to select a random element.
