Consider the following string transformation:

1. append the character # to the string (we assume that # is lexicographically smaller than all other characters of the string)
2. generate all rotations of the string
3. sort the rotations in increasing order
4. based on this order, construct a new string that contains the last character of each rotation

For example, the string babc becomes babc#. Then, the sorted list of rotations is #babc, abc#b, babc#, bc#ba, and c#bab. This yields a string cb#ab.

Input

The only input line contains the transformed string of length n+1. Each character of the original string is one of a–z.

Output

Print the original string of length n.

Constraints

• 1 \le n \le 10^6

Example

Input:

cb#ab

Output:

babc
