|VK Cup 2012 Wild-card Round 1|
You are given a string. Remove all digits from it. When a character is removed from a string, all characters to the right of it are shifted one position to the left.
The only line of input contains a string between 1 and 100 characters long. Each character of the string has ASCII-code between 33 (exclamation mark) and 126 (tilde), inclusive.
Output the given string with all digits removed from it. If the original string had only digits, output an empty string.
