Star Pattern Printing

Given an integer n (\(1 \leq n \leq 20\)), write a program to print a star pattern consisting of n lines. On the \(i\)-th line, print i instances of the string "* " (an asterisk followed by a space). The output must exactly match the described format.

Example:

Input:
3
Output:
*

inputFormat

The input is provided via stdin and consists of a single integer n on one line, where \(1 \leq n \leq 20\).

outputFormat

The output should be printed to stdout and consists of n lines. The \(i\)-th line should contain i copies of the string "* ", ending with a newline character.
