Formally, let be if contains in base and otherwise. A positive integer must be skipped when for some positive integers and such that .
For example, if R says , because is skipped, J should say after . If R says , because and , J should say after . If R says , because all numbers from to contain , J should say after .
Input Specification

Output one line for each test case.
If R says a number that should be skipped, output -1
. Otherwise output the number J should say after R.
