Goal
Your program must output a minified version of a CodinGame script formatted as CGS.
To do so, except for names between apostrophes ('), remove spaces, tabulations and display the code on one line.
In addition, variables written between two ($) must be minified, the first variable of the script will be $a$, the second one $b$, etc.
Input
Line 1: The number N of CGS lines to be minified.
The N following lines: The CGS content.
Output
Line 1: The minified CGS content.
Constraints
0 < N < 10
0 ≤ number of variables in CGS content < 10
Example
Input
4
(
$hello$ = 'hello';
print $hello$;
)
Output
($a$='hello';print$a$;)
