# Enthusiastically Russianify a String

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 + $Suffix } Get-RussianString "codegolf" 0.5 codegolf))))  This is so shortest code wins! • I'm confused, do Russians really use ) for emphasis like an !? Is it some encoding issue? Jan 30 '17 at 16:25 • @CaptainMan I believe it's more like smiley faces than !s, but they do type them as is, it's not super common, but it's quite iconic. Jan 30 '17 at 16:47 • @CaptainMan No ) is reduced emoticon :). It is used very common between young people as far as I know. Jan 30 '17 at 17:23 • ) is not an emphasis, it is simply the smiley. As far as I know, it is harder to type : when using Russian keyboard layout, therefore they smile without eyes. Jan 30 '17 at 17:28 • @Juris it's as hard to write : on Russian layout (ЙЦУКЕН) as it is to type ^ on QWERTY. But indeed, the ) is a reduced version of :). It's much easier to press and hold Shift-0 than to repeatedly alternate keys. Jan 30 '17 at 18:12 ## 36 Answers # Perl 6, 21 bytes {$^a~")"x$^b*$a.comb}

Uses the decimal format.

### How?

ȮL×Ċ”)x - Main link: string, decimal
Ȯ       - print string
L      - length(string)
×     - multiply by the decimal
Ċ    - ceiling (since rounding method is flexible)
”)  - a ')' character
x - repeated that many times
- implicit print

• @ConnorLSW I just noticed that this will print the required string as a full program, but that the specification states "return" - is this OK? Jan 30 '17 at 15:34
• any standard accepted output format is fine Jan 30 '17 at 16:51
• no worries - this is my first challenge so there's a few of these things that I missed, i've updated it in the question to be more clear - thanks for asking. Jan 30 '17 at 17:04

## Common Lisp, 5952 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).

• (())/10 not enough parentheses Jan 31 '17 at 13:40
• Who thought this language is a good idea? Jan 31 '17 at 16:14
• Scheme's format accepts a decimal argument to v. Maybe Common Lisp's does, too? Feb 1 '17 at 8:13
• @MichaelVehrs Indeed, thanks a lot. Feb 1 '17 at 8:19
• @coredump Actually, I should have said "Guile's format accepts ...", since standard Scheme format does not support ~r; and Guile's format follows the example of Common Lisp's. Feb 1 '17 at 10:14

# JavaScript ES6, 3831 30 bytes

s=>n=>s+')'.repeat(s.length*n)


f=s=>n=>s+')'.repeat(s.length*n)

console.log(f("hi!")(4.99))

• Nice, I think that's the shortest possible. You can save a byte through currying: s=>n=>s+')'.repeat(s.length*n) (it would then be called like f("hi!")(4.99)) Jan 30 '17 at 15:30

The top line reads characters (i) until it finds a newline (ASCII 10, a), then goes down (v).

Then we discard one character (the newline) with ~, push the length of the stack (l), read a float (I), multiply the two, and repeatedly (R) push the character ")" that many times. Finally, reverse the stack (r), output it and halt (H).

Literally the first Lisp program I've ever written! I'm already having fun.

• 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)\))))). May 5 '17 at 11:58
• Also, the current state of your code doesn't work, (#(...) "codegolf" 125) must add 125 percent of the length of "codegolf" instead of 125 times the length of "codegolf". So, the fixed program would be: #(str %(apply str(repeat(*(count %)%2 1/100)\))))`, which is 49 bytes. May 5 '17 at 12:01
