title: How to find sequential items in an array using lua?
body: <p>I need a piece of code in lua language that can find sequential items in an array that the number of item in the group exceeds a specific nubmer. Example:if I have the array(the numbers won't be in the right order, randomly distributed)->( 2,5,9,10,11,21,23,15,14,12,22,13,24 )  ; there are two sequential groups (9,10,11,12,13,14,15) and (21,22,23,24 ) . I want the first group to be found if the specific number say (4) or more, or I can get the two groups if the number is (3) or less for example.
  thanks</p>
