for loop position rotation

Question

User-1279294283 posted

Does anyone know how to create this sequence using a for loop and/or nested for loops? I'm having trouble. Thanks

1	2	3	4	5	6	7	8	9	10	11
2	3	4	5	6	7	8	9	10	11	1
3	4	5	6	7	8	9	10	11	1	2
4	5	6	7	8	9	10	11	1	2	3
5	6	7	8	9	10	11	1	2	3	4
6	7	8	9	10	11	1	2	3	4	5
7	8	9	10	11	1	2	3	4	5	6
8	9	10	11	1	2	3	4	5	6	7
9	10	11	1	2	3	4	5	6	7	8
10	11	1	2	3	4	5	6	7	8	9
11	1	2	3	4	5	6	7	8	9	10

Yep here it is:

        Dim MyIntList As New List(Of Integer)

        Dim x As Integer = 1
        For j As Integer = 1 To 11
            For i As Integer = x To 11
                MyIntList.Add(i)
                If (x > 1) And (i = 11) Then i = 0
                If (x > 1) And (i = (x - 1)) Then Exit For
            Next
            x += 1
        Next

An interview or logic question by chance.  I didn't recognize a number pattern I am familiar with (which is almost none) so if that is a know pattern they may be a mathematically better way to solve this problem. There is probably other ways to refine the code, but what I provided you will spit out those 121 numbers in the exact order you provided.

Hope this helps!

Thanks atconway! It's for a employee rotation. each number represents a job postion in the rotation.
