In the keyPressed() handler, handle the following keys:
- When the 'f' key is pressed, fill the array with random values (0.0 to 100.0) and set wbig to -1.

- When the 'm' key is pressed, move the biggest element to the end (swapping, to retain all values).
- When the 'S' key is pressed, sort the entire array (in ascending order).
Now, add buttons to be clicked on, instead of using keys.
