I am getting wrong answer although in the dry run everything seems to be working fine. Also, the sample test cases from editorial are working.

Can anyone suggest the test case which could fail my solution/ review my solution?

TestCases:

1 1 1 => -1 (since x>1)

1 2 20122 30183 => 10061

1 1 24371 => 24371

1 2 123 456 => 3

Many Thanks!
