Professor X got lost in a maze of an ancient tomb in Egypt. While he was finding the way to escape, he got a message of the tomb builders on the old walls:
- The code to open the exit door is the sequence C of n digits formed c1..cn (ci∈[0,9] ).
- For every sequence C, combining with the given integers A,B, call:
- hi=(hi-1×A+ci) mod B
- The smallest sequence C (in lexicological order) satisfying hn=G (where G is a given integer) is the exit code which professor X needs.
Give the integers n,A,B,G, help professor X find out the exit code!
One and only line contains the integers n,A,B,G, respectively, each of them is separated with at least one space character.
Output in a single line the exit code found.
3 11 111 92
- The input satisfies that the answer always exist.
