PROGRAMMING:Digital encryption
Input a four digit number and output it after encryption. The method is to add 9 to each digit of the number, and then divide it by 10 to take the remainder as the new digit of the bit. Finally, the thousand digit and ten digit are exchanged, and the hundred digit and individual digit are exchanged to form the new four digit after encryption. For example, input 1257, add 9 to get the new number 0146, and then transpose twice to get 4601.
###Input format:
Enter a four digit integer x in one line, that is, the number to be encrypted.
###Output format:
In one line, output the new number V after encryption according to the format "the encrypted number is V".
###Input example:
```in
one thousand two hundred and fifty-seven
```
###Output example:
```out
The encrypted number is 4601
```
