| <code class="computeroutput"><span class="identifier">next_permutation</span></code> transforms |
| the range of elements <code class="computeroutput"><span class="identifier">rng</span></code> |
| into the lexicographically next greater permutation of the elements if |
| such a permutation exists. If one does not exist then the range is transformed |
| into the lexicographically smallest permutation and <code class="computeroutput"><span class="keyword">false</span></code> |
| is returned. <code class="computeroutput"><span class="keyword">true</span></code> is returned |
| when the next greater permutation is successfully generated. |
| </p> |
| <p> |
| The ordering relationship is determined by using <code class="computeroutput"><span class="keyword">operator</span><span class="special"><</span></code> in the non-predicate versions, and |
