It is said that the famous Somali Pirates hate digits. So their QQ passwords never contain any digit. Given some lines of candidate passwords, you are asked to delete all the digits in the passwords and print other characters in their original order. So the Somali Pirates can use them as their QQ passwords^^

Each case contains a line indicating a candidate password. The length of the password is between 1 and 20, inclusive. Besides, the password consists of only digits and English letters.
