7. Cypher

Fifi receives a journal from her older brother as a gift. To open it, she needs to enter a cypher, a natural number consisting of 4 digits. Her brother tells her a four-digit number and specifies that the cypher is the largest number obtained from it by a circular permutation of the digits by one position. Knowing the number, help Fifi find the cypher to open the journal.
Example: if the number given by Fifi's brother is 1234, the cypher is 4123 (the circular permutations are 2341, 3412, 4123, 1234, and the maximum is 4123).
