The algorithmic package lets me make a while loop as

  \While{$u\neq v$}
    \State Something

which results in a

while(u is not v) do 
end while 

How can I make a do-while loop which result in

while(u is not v)

(Sorry for the lack of output. I don't know how to add that to my question. I hope the question and the intention is clear enough) I use document class memoir and packages algpseudocode and algorithm.

    There's a \Repeat <text> \Until{<condition>} construct, if that helps. Same meaning as do...while, just different words. May 23 '13 at 9:03

    @JohnWickerson Well, strictly speaking, those two constructs do not have the same meaning, since, for the two loops to be equivalent, the condition used after "until" would have to be the negated version of that used after "while".

    Whoops! Good spot :) May 23 '13 at 10:12

You have to define the do-while construct yourself; see below.

Note: you tagged your question with algorithmicx, not algorithmic, so I produced an answer using the algorithmicx package.

enter image description here


\algdef{SE}[DOWHILE]{Do}{doWhile}{\algorithmicdo}[1]{\algorithmicwhile\ #1}%

    \State Something
  \doWhile{$u \neq v$} % <--- use \doWhile for the "while" at the end
