Tin whistle Tin whistle The tin whistle, also called the penny whistle, English flageolet, Scottish penny whistle, tin flageolet, Irish whistle, Belfast Hornpipe, (or simply ) and Clarke London Flageolet is a simple, six-holed woodwind instrument. It is a type of fipple flute, putting it in the same class as the recorder, Native American flute, and other woodwind instruments that meet such criteria. A tin whistle player is called a tin whistler or simply a whistler. The tin whistle is closely associated with Celtic music. The tin whistle in its modern form is from a wider family of fipple flutes which have
Finger search in rank. If "x" and "y" are the "i"th and "j"th largest elements in the structure, then the difference in rank is |"i" - "j"|. If a normal search in some structure would normally take O(f("n")) time, then a finger search for "x" with finger "y" should ideally take O(f("d")) time. Remark that since "d" ≤ "n", it follows that in the worst case, finger search is only as bad as normal search. However, in practice these degenerate finger searches do more work than normal searches. For instance, if f("n") is log("n"), and finger search does twice as many comparisons
