Given a string of ASCII letters (upper and/or lower case), output the raw MathJax required to display that string bifurcating at each character, into superscripts and subscripts. For example, the inputs cat
and horse
would result in outputs which MathJax renders as the following, respectively:
Note that only one input is required to be taken - these two are listed side by side simply to save vertical space.
Markup meaning
_
indicates a subscript.^
indicates a superscript.- Braces are required around superscripted or subscripted substrings that contain further superscripting or subscripting in order to prevent them all being at the same level.
Test cases
Test cases are in the format input : output
. The first test case shows the empty string as input should result in the empty string as output.
"" : ""
"a" : "a"
"me" : "m_e^e"
"cat" : "c_{a_t^t}^{a_t^t}"
"frog" : "f_{r_{o_g^g}^{o_g^g}}^{r_{o_g^g}^{o_g^g}}"
"horse" : "h_{o_{r_{s_e^e}^{s_e^e}}^{r_{s_e^e}^{s_e^e}}}^{o_{r_{s_e^e}^{s_e^e}}^{r_{s_e^e}^{s_e^e}}}"
"bifurcate" : "b_{i_{f_{u_{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}^{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}}^{u_{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}^{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}}}^{f_{u_{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}^{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}}^{u_{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}^{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}}}}^{i_{f_{u_{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}^{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}}^{u_{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}^{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}}}^{f_{u_{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}^{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}}^{u_{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}^{r_{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}^{c_{a_{t_e^e}^{t_e^e}}^{a_{t_e^e}^{t_e^e}}}}}}}"
You can see how these are rendered by pasting the output into mathurl.com.
No redundant braces
MathJax will happily render markup that has redundant braces. For example, the following will all look identical when rendered: a
, {a}
, {}{a}
, {{{{a}}}}
.
However, valid output for this challenge has no redundant braces. Note in particular that single characters in the output are not surrounded by braces.
Order
The order of subscript and superscript is unimportant. The following are equivalent and will be indistinguishable when rendered (and are all equally valid outputs):
c_{a_t^t}^{a_t^t}
c_{a^t_t}^{a_t^t}
c_{a_t^t}^{a^t_t}
c_{a^t_t}^{a^t_t}
c^{a_t^t}_{a_t^t}
c^{a^t_t}_{a_t^t}
c^{a_t^t}_{a^t_t}
c^{a^t_t}_{a^t_t}
Scoring
For each language, the winner is the shortest code in bytes.

to unsubscript huh who said I want to unsubscript or something? It was a test to see if I read the whole post right? – Erik the Outgolfer – 2017-08-09T15:39:42.96012@EriktheOutgolfer no it was just a very bad joke. – trichoplax – 2017-08-09T15:49:21.700
Can we just output the compiled pdf result instead? I would like to write a pure Latex answer. – Post Rock Garf Hunter – 2017-08-09T17:24:15.080
@WheatWizard that sounds like a different challenge. It wouldn't be valid as an answer here. – trichoplax – 2017-08-09T21:14:57.953
