Nodir NAZAROV Komilijonovich [TUIT-Karshi] Little trick: if you are getting W3, or W5 or whatever [2] // Problem 2023. Donald is a postman 5 Dec 2014 02:50

use simple algorithm:
- checks only initial.
- keep state of previous
- initial state of previous is 1, since postman is in leftmost case

useful test cases:

----
1
Bambi

1 (not 0, because he moves to second case with one step)
----
1
Alice

0
----
1 Dumbo

2
---

Didn't get your testcase; if Bambi, Alice and Dumbo are the Kids, the answer should be 3, right?
