Many of you may have interacted with people from Russia on the internet at some point, and a subset of you may have noticed the slightly odd method they have of expressing themselves.

e.g. удали игру нуб)))

where the ))) are added for emphasis on the previous statement, I have been working on a theory that the ratio of )'s to the rest of the string is directly proportional to the amount of implied emphasis, however I oftentimes find it difficult to compute the ratio on the fly, as I am also trying to cope with a slew of abuse, so I would like the shortest possible code to help me calculate what the resulting string should be, for a value of enthusiasm between 0 and 500%, given the original, unenthusiastic string, this will aid my research greatly as I will not have to type out bulky scripts every time I wish to test my hypothesis.

So, the challenge:

write a full program or function, which, provided two arguments, a string of unknown length, and a number, in either integer format (between 0 and 500) or in decimal format (between 0 and 5, with 2 points of accuracy) will

  • return/display the original string, suffixed with a number of )'s
  • the number will be the calculated as a ratio of the input number to the string length.
  • so if the number 200, or 2.00 was provided, 200% of the string must be suffixed as )'s
  • the number of brackets rounded to in decimal situations does not matter.
  • script is required to support Printable ASCII characters.
  • only has to support one input number format, of your choice.

Examples:

"codegolf" 125      = codegolf))))))))))
"codegolf" 75       = codegolf))))))
"noob team omg" 0.5 = noob team omg))))))
"hi!" 4.99          = hi!)))))))))))))))

Example code (PowerShell) (with decimal input):

Function Get-RussianString ([string]$InputStr,[decimal]$Ratio){
    $StrLen = $InputStr.Length
    $SuffixCount = $StrLen * $Ratio
    $Suffix = [string]::New(")",$SuffixCount)
    return $InputStr + $Suffix
}

Get-RussianString "codegolf" 0.5
codegolf))))

This is so shortest code wins!

Common Lisp, 59 52 50

Parentheses? I am in.

(lambda(s n)(format()"~a~v@{)~}"s(*(length s)n)0))

Details

(lambda(s n)               ; two arguments (string and ratio)
  (format ()               ; format as string
          "~a~v@{)~}"      ; control string (see below)
          s                ; first argument (string)
          (* (length s) n) ; second argument (number of parens)
          0))              ; one more element, the value does not matter

Format control string

  • ~a : pretty print argument (here the given string)
  • ~v@{...~} : iteration block, limited to V iteration, where V is taken as an argument, namely the (* ...) expression. The iteration is supposed to iterate over a list, but when you add the @ modifier, the list is the remaining list of arguments to the format function. There must be at least one element in the iterated list (otherwise we exit, disregarding V). That is why there is an additional argument to format (0).

Since no element in the list is consumed by the format, the loop is infinite but fortunately, it is also bounded by V, a.k.a. the number of parentheses to be printed.


Edit: thanks to Michael Vehrs for pointing out that there is no need to round the numerical argument (the question allows to truncate/round however we want, so the default behavior works here).

Not-so-boring solution (64 bytes) :

#(.replace(str(nth(iterate list(symbol %))(*(count %)%2)))"(""")

Converts input string to a symbol (to get rid of quotes) and repeatedly applies function list on it generating infinite sequence like this: (a (a) ((a)) (((a))) ... ). Takes nth element converts it to string and replaces all opening parentheses with nothing.

SimpleTemplate, 92 bytes

Takes the string as the first parameter and the "ratio" as the second.
The ratio is between 0 and 5, with 2 decimal places.

{@echoargv.0}{@callstrlen intoL argv.0}{@set*Y argv.1,L}{@callstr_repeat intoO")",Y}{@echoO}

As you can see, it is non-optimal.
The 2 {echo} there could be reduced to 1.
Due to a bug in the compiler, this code can't be reduced much further.


Ungolfed:

{@echo argv.0}
{@call strlen into length argv.0}
{@set* ratio argv.1, length}
{@call str_repeat into parenthesis ")", ratio}
{@echo parenthesis}

If no bug existed, the code would look like this, 86 bytes:

{@callstrlen intoL argv.0}{@set*Y argv.1,L}{@callstr_repeat intoO")",Y}{@echoargv.0,O}

  • \$\begingroup\$ Welcome to the world of Lisp! :P In Clojure, you can use the condensed form of anonymous functions #(...), and you can get rid of the print (since function returns should be acceptable). You can change reduce to apply for the str function, and you can change ")" to \), which does the same thing. So, the final code should be: #(str %(apply str(repeat(*(count %)%2)\))))). \$\endgroup\$ – clismique May 5 '17 at 11:58
