1575 <p>This reordering has the additional property that any value at position <code>i < index</code> will be
1576 less than or equal to any value at a position <code>j > index</code> using the key extraction function.
1577 Additionally, this reordering is unstable (i.e. any number of equal elements may end up at
1578 position <code>index</code>), in-place (i.e. does not allocate), and runs in <em>O</em>(<em>n</em>) time.
1579 This function is also known as “kth element” in other libraries.</p>
1580 <p>It returns a triplet of the following from
1581 the slice reordered according to the provided key extraction function: the subslice prior to
1582 <code>index</code>, the element at <code>index</code>, and the subslice after <code>index</code>; accordingly, the values in
