Problem 60734. Conditional transpose

Created by Christian Schröder

Solve Later

You're given two vectors of the same length, x and y, which might be row or a column vectors. Your task is to ensure that y has the same "rowishness" as x: y should be a row vector if x is a row vector, and a column vector if x is a column vector.
Control flow statements (if, switch, for, while, try) and recursion aren't allowed. Neither are arrayfun and friends (cellfun, structfun, varfun, rowfun, spfun). Cheating is possible but made harder, and in any case discouraged.

Christian, I would suggest you to update the check for if condition statement to 'if ' (i.e. with a space at the end), as there are functions containing the string 'if' , which are allowed, but fail with the current anti-cheat test suite.

Same for problem #60736. Conditional transpose II.

@Dyuman thanks for the tip. I avoided checking for "if " since it's also possible to write "if(condition)", but perhaps I could just check for both "if " and "if(". That, or try to work with the parse tree instead of fishing for textual matches...

@Dyuman I've updated the test suite, so using functions with "if" in their names should now work. Existing solutions have been rescored.

@Dyuman I've updated the test suite to check for banned keywords/functions based on the parse tree. Hopefully this'll be more robust and cause fewer false positives.
