Encode with ROT13.5
- Encode with ROT13.5 [FINALIZED]
- Given a string, convert all of its letters using ROT13, and all of its digits using ROT5. This is sometimes referred to as [ROT13.5](https://en.wikipedia.org/wiki/ROT13#Variants "Variants of ROT13 on Wikipedia").
- ## Input
- - A sequence of printable ASCII characters (character codes 32 to 126 inclusive)
- - This may be a string or any data structure of characters
- ## Output
- - A sequence of characters
- - This may be a string or any ordered data structure of characters. It does not need to match the input format (provided it is consistent between inputs)
- - For example, you may take input as an array of characters, and output as a string, provided this format does not change for different inputs
- - Each character in the output will be determined by the character in the corresponding position in the input, as follows:
- - A lower case letter will be replaced with the lower case letter 13 character codes after it, wrapping back to 'a' if 'z' is exceeded
- - An upper case letter will be replaced with the upper case letter 13 character codes after it, wrapping back to 'A' if 'Z' is exceeded
- - A numeric digit will be replaced with the numeric digit 5 character codes after it, wrapping back to '0' if '9' is exceeded
- - Any other character will remain unchanged
- ## Conversion table
- Here is the output character for every valid input character, in the format `input : output` (the first character is a space, which remains unchanged):
- ```text

- ! : !
- " : "

- ## Test cases
- Test cases are in the format `"input string" : "output string"`.
- ```text
- "gnat irk terra" : "tang vex green"
- "2468" : "7913"
- "#%&@,.:;?" : "#%&@,.:;?"
- "Rot13 & Ebg68" : "Ebg68 & Rot13"

Encode with ROT13.5
Given a string, convert all of its letters using ROT13, and all of its digits using ROT5. This is sometimes referred to as [ROT13.5](https://en.wikipedia.org/wiki/ROT13#Variants "Variants of ROT13 on Wikipedia"). ## Input - A sequence of printable ASCII characters (character codes 32 to 126 inclusive) - This may be a string or any data structure of characters ## Output - A sequence of characters - This may be a string or any ordered data structure of characters. It does not need to match the input format (provided it is consistent between inputs) - For example, you may take input as an array of characters, and output as a string, provided this format does not change for different inputs - Each character in the output will be determined by the character in the corresponding position in the input, as follows: - A lower case letter will be replaced with the lower case letter 13 character codes after it, wrapping back to 'a' if 'z' is exceeded - An upper case letter will be replaced with the upper case letter 13 character codes after it, wrapping back to 'A' if 'Z' is exceeded - A numeric digit will be replaced with the numeric digit 5 character codes after it, wrapping back to '0' if '9' is exceeded - Any other character will remain unchanged ## Conversion table Here is the output character for every valid input character, in the format `input : output` (the first character is a space, which remains unchanged): ```text : ! : ! " : " # : # $ : $ % : % & : & ' : ' ( : ( ) : ) * : * + : + , : , - : - . : . / : / 0 : 5 1 : 6 2 : 7 3 : 8 4 : 9 5 : 0 6 : 1 7 : 2 8 : 3 9 : 4 : : : ; : ; < : < = : = > : > ? : ? @ : @ A : N B : O C : P D : Q E : R F : S G : T H : U I : V J : W K : X L : Y M : Z N : A O : B P : C Q : D R : E S : F T : G U : H V : I W : J X : K Y : L Z : M [ : [ \ : \ ] : ] ^ : ^ _ : _ ` : ` a : n b : o c : p d : q e : r f : s g : t h : u i : v j : w k : x l : y m : z n : a o : b p : c q : d r : e s : f t : g u : h v : i w : j x : k y : l z : m { : { | : | } : } ~ : ~ ``` ## Test cases Test cases are in the format `"input string" : "output string"`. ```text "gnat" : "tang" "2468" : "7913" "Rot13" : "Ebg68" "Ebg68" : "Rot13" "#%&@,.:;?" : "#%&@,.:;?" ```
