[Coco] Perplexity

[Tony Schountz]

Well, I just asked perplexity to write a BASIC09 bubble sort procedure and this is what it generated. Not perfect but easy enough to edit. 

Certainly! Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order. Below is a BASIC09 procedure to implement the bubble sort algorithm:
text
PROCEDURE BubbleSort
  DIM array(10) : REM Define an array of 10 elements
  DIM i, j, temp

  REM Initialize the array with some values
  FOR i = 0 TO 9
    PRINT "Enter value for element "; i + 1; ": ";
    INPUT array(i)
  NEXT i

  REM Bubble sort algorithm
  FOR i = 0 TO 8
    FOR j = 0 TO 8 - i
      IF array(j) > array(j + 1) THEN
        temp = array(j)
        array(j) = array(j + 1)
        array(j + 1) = temp
      END IF
    NEXT j
  NEXT i

  REM Print the sorted array
  PRINT "Sorted array:"
  FOR i = 0 TO 9
    PRINT array(i)
  NEXT i
END

Explanation:
Array Initialization: The procedure begins by defining an array with 10 elements. The user is prompted to enter values for each element of the array.
Bubble Sort Logic: The outer loop runs from 0 to 8, and the inner loop runs from 0 to 8 minus the current index of the outer loop. This ensures that after each pass, the next largest element is placed in its correct position.
Swapping Elements: If the current element is greater than the next element, they are swapped using a temporary variable.
Output: After sorting, the sorted array is printed.
This procedure sorts the array in ascending order. You can modify it to sort in descending order by changing the comparison operator from > to <.
