# 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? – Captain Man 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. – colsw Jan 30 '17 at 16:47 • @CaptainMan No ) is reduced emoticon :). It is used very common between young people as far as I know. – talex 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. – Džuris 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. – Ruslan Jan 30 '17 at 18:12 ## 36 Answers # C++14, 43 bytes As unnamed lambda modifying its input, assuming s is similar to std::string (has .append(int,char) and assuming p to be of floating point type: [](auto&s,auto p){s.append(s.size()*p,41);}  Usage: #include<string> #include<iostream> auto f= [](auto&s,auto p){s.append(s.size()*p,41);} ; int main() { std::string s = "abcdefghijk"; f(s,0.75); std::cout << s << std::endl; }  # Haskell, 37 bytes s!n=s++([1..div(n*length s)100]>>")")  Try it online!

Takes input as decimal, then newline, then string. Try it online!

## Explanation

Let's start from the bottom.

I


A raw string read from STDIN.

#
I


The length of the string.

*i
#
I


Multiply it by a number read from STDIN (the number is read first, since i comes before I in the source).

$') *i # I  Repeat the character ) that many times, rounding down. ,$')
*i
#
EI


Append to the original string (the , looks for arguments from the south and east, and E tells the southward seeker to turn east, where it finds the I).

P
,\$')
*i
#
EI


Print the resulting string.

# Mathematica, 24 bytes

#<>Table[")",#2Tr[1^#]]&


Unnamed function taking a list of characters and a decimal number as input and returning a string. Tr[1^#] is a sneaky golfy way to calculate the length of a list, so #2Tr[1^#] computes the required number of parentheses. Table[")",...] produces a list of that many right parentheses (all decimals automatically rounded down, which is nice). Finally, #<> concatenates the input string to the parentheses, flattening the list produced by Table as it goes.

• That's quite cheaty, taking the string as a list of characters, but returning as a multi-character string. For consistent IO formats you could replace <> with ~Join~ at a cost of 4 bytes – LLlAMnYP Feb 1 '17 at 12:34
• I'd be interested in a community judgment on this issue. If it's cheating, then of course I'll avoid this type of mismatch. But if it's just cheaty - well, it seems to me that cheaty is very much on topic for this site :) – Greg Martin Feb 1 '17 at 17:37
• The challenge specification is sufficiently vague: return/display the original string, suffixed with a number of )'s (though I'd be picky with original string). Many other challenges specifically state "I/O formats must be consistent". If it's not a default rule, I guess you're in the white-enough part of the gray area. – LLlAMnYP Feb 2 '17 at 7:46
• @LLlAMnYP community consensus applies for I/O methods, so I believe this is valid Mathematica – colsw Feb 2 '17 at 13:39

Try it

# GNU AWK, 59 bytes

{t=sprintf("%"n*length(s)"s","");gsub(/ /,")",t);print s t}


Accepts arguments on command line (using the decimal form) like so:

: | awk -v s="codegolf" -v n=0.75 -f russianify.awk


Yes, AWK requires something to be attached to stdin, even if that something is 0 bytes returned by the no-op shell builtin. You could also use echo | awk ..., or really anything that doesn't contain a newline.
