Alewife of many native species of fish. In an effort to control them biologically, Pacific salmon were introduced, only partially successfully. As a marine fish, the alewife is a US National Marine Fisheries Service "Species of Concern". Alewives reach a maximum length of about 40 cm (16 in), but have an average length of about 25 cm (10 in). The front of the body is deep and larger than other fish found in the same waters, and its common name is said to come from comparison with a corpulent female tavernkeeper ("ale-wife"). In southwestern Nova Scotia, it is called a kiack
Block sort can be used to sort the contents of the second internal buffer, including unstable sorts like quicksort, since the contents of the buffer are guaranteed to unique. Insertion sort is still recommended, though, for its situational performance and lack of recursion. Block sort is a well-defined and testable class of algorithms, with working implementations available as a merge and as a sort. This allows its characteristics to be measured and considered. Block sort begins by insertion sorting groups of 16–31 items in the array. Insertion sort is an operation, so this leads to anywhere from to , which is once
