The public rank is one-based, whereas `Find` uses a zero-based index:

``
function Select(i; var a; N): T
    require 1 <= i <= N
    return Find(i-1,a,0,N)
``

Thus \b[rank $i$ is index $i-1$]. The boundary ranks return the minimum and maximum, and repeated values occupy as many ranks as their multiplicities in the <multiset>.
