The sorting and partitioning algorithms provide various strategies for ordering the elements of a sequence.
Each of the sorting and partitioning algorithms provides stable and unstable versions (§ 10.3.1, p. 387). A stable algorithm maintains the relative order of equal elements. The stable algorithms do more work and so may run more slowly and use more memory than the unstable counterparts.
Partitioning Algorithms
A partition divides elements in the input range into two groups. The first group consists of those elements that satisfy the specified predicate; the second, those that do not. For example, we can partition elements in a sequence based on whether the elements are odd, or on whether a word ...
