State Code From Registration Number

Accept the registration number of a vehicle as input and print its state-code as output.

Sample registration numbers:

• TN-10-AB-2010
• HR-15-XZ-1999

Every registration number follows this same template, so the state-code is always the first two characters.

Input

A single line containing the registration number.

Output

A single line: the two letter state-code.

Example

Input:

TN-10-AB-2010

Output:

TN
