Print Indented String

Given a string s, print each character of the string on a new line. The first character is printed without any leading dots. Each subsequent character is preceded by an increasing number of dots. Specifically, for the i-th character (0-indexed), print i dots followed by the character.

For example, if s = "hello", the output should be:

$$ \begin{array}{l} h \\ .e \\ ..l \\ ...l \\ ....o \end{array} $$

This problem will test your ability to manipulate strings and output formatting based on input.

inputFormat

The input consists of a single line containing the string s. The string may include spaces and other printable characters.

outputFormat

Output each character of the string s on a separate line. The i-th line (0-indexed) should contain i dots ('.') immediately followed by the i-th character of the string.

## sample

hello

h
.e
..l
...l
....o
