Because having a problem statement is too mainstream...:P
Hint: Observe the sample input and output 

Input

Contains few test cases with each test case containing a string in a seperate line.String will consist of lowercase alphabets. ('a'-'z') only and strlen(string) <=500

For taking input read till EOF.

An example of how to read strings till EOF:

while(gets(string))

{

/*process string*/

}

Score is the length of your code. (Smaller the code length,better the score)

Output

For each test case output a single string containing the answer

Example

Input:
lolo

whoami

Output:

oror
oror
zkrdpl
