String Transform

• Time limit: 1.00 s
• Memory limit: 512 MB

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:
