Caesar Cipher Decryption for Digit Strings

You are given a string of digits that has been encrypted using a Caesar cipher with a shift of 3. The decryption process calculates the original digit using the formula: \( (x - 3) \mod 10 \). For example, if a digit '0' is encountered, the decrypted value is '7'.

Your task is to implement a program that reads the encrypted string from standard input and outputs the decrypted string to standard output.

inputFormat

The input consists of a single line containing a non-empty string of digits. There are no spaces in the input.
