< code class = "computeroutput" > < span class = "identifier" > partition< / span > < / code > orders the
elements in < code class = "computeroutput" > < span class = "identifier" > rng< / span > < / code > based
on < code class = "computeroutput" > < span class = "identifier" > pred< / span > < / code > , such that the
elements that satisfy < code class = "computeroutput" > < span class = "identifier" > pred< / span > < / code >
precede the elements that do not. In the versions that return a single
iterator, the return value is the middle iterator. In the versions that
have a configurable range_return, < code class = "computeroutput" > < span class = "identifier" > found< / span > < / code >
corresponds to the middle iterator.
