What do you asking exactly? Some detail please?

The start point is 2 , and the finish point is 3.

Katas description is telling everything.
Can you read the description please?

v e t u r v e l
|         |   |
1         2   3

Order is the same

v e l i v e l
|   |   |
1   3   2

Order is not the same, because if we get the same pattern letter then we should find second occurrence of the same letter In that case we found first 'v', second 'v', and first 'l'
