Hello monks!
In my code, after some lines, I end up with an array similar to this: 
141326478
103194415
86004442
86004438
86004437
86004434
86004431
85280835
85280834
85280832
53250112
50137387
50137382
50137380
29223108
25694155
17916134

What I want to do is the following : create sub-arrays, where elements that are within the range of -1000 to +1000 of each other, will be put in the same sub-array. For example, 141326478 will be alone, since no other element of this array is -1000 to +1000 from that one, whereas 50137387, 50137382 and 50137380 will be grouped together.
I am really struggling with this for quite some time now and I have no idea on how to proceed. Any advice or snippet of code will be highly appreciated!
