Minimum Cost to Convert Stars to Hashes

You are given a string s that consists solely of the characters '*' and '#'. Your task is to determine the minimum cost to convert all '*' characters into '#' characters. Each conversion of a '*' to a '#' incurs a cost of 1. Therefore, if there are N occurrences of '*' in the string, the total cost will be \(cost = N\).

Your program should read the input string from stdin and output the computed cost to stdout.

inputFormat

A single line containing a non-empty string s composed only of the characters '*' and '#'.

outputFormat

Output a single integer which represents the minimum cost required to convert all '*' characters to '#' in the string.
