Hi Vikram

The idea of this app is to provide a random fact each time, of course this does mean that the same fact can appear for any number of times in a row as the chance of getting a 5 say is 1/10 each time and doesn't change on any subsequent calla to obtain a random number.

The workaround would be to create 2 arrays and move the selected fact from your original array to the second array. Once the original array is empty choose from the second array and repeat the process in reverse. While this is possible it would mean additional coding which is not covered in this tutorial, but perhaps try it out for yourself once you've got the finished product to try and polish it.

Hope this helps


Thank ya Daniel!!
