sv
A very simple and fast spam detection mechanism is based on the ratios between whitespace characters, lowercase letters, uppercase letters, and symbols. Symbols are defined as characters that do not fall in one of the first three groups.
Input
The input consists of:
-
one line with a string consisting of at least $1$ and at most $100\, 000$ characters.
A preprocessing step has already transformed all whitespace characters to underscores (_), and the line will consist solely of characters with ASCII codes between 33 and 126 (inclusive).
Output
Output four lines, containing the ratios of whitespace characters, lowercase letters, uppercase letters, and symbols (in that order). Your answer should have an absolute or relative error of at most $10^{-6}$.
