Try this input:

1
4
8
0 1
1 2
2 3
3 0
2 4
4 2
3 4
4 3

This is not cactus, but for every node in-degree equals to out-degree.
Am I right?

Read the post of Adrian Kuegel!

Try to mark initial cell as empty '0' before output the result.

10500 - Robot maps

The problem seems to be easy but I got WA many times. So some questions: 1. What character is used to mark an empty cell of the map: is it a zero digit '0' or is it a letter 'O'? I tried both and always got WA. 2. What may be the trick? Can somebody give us a hint? Many thanks in advance!!
