Replace Digits with Asterisk

You are given a string s. Your task is to remove all contiguous sequences of digits (i.e., characters between 0 and 9), and replace each such sequence with a single asterisk character *. In other words, every maximal substring that matches the regular expression $\d+$ should be replaced by *.

For example, the input a123b456c789 should be transformed into a*b*c*.

Note that the input string may contain uppercase and lowercase letters along with digits, and its length is in the range 1 ≤ |s| ≤ 1000.

inputFormat

The input consists of a single line containing a non-empty string s (1 ≤ |s| ≤ 1000). The string may include digits and alphabetical characters.
