Lamzdeliai and twisted off of the wood. The blowing end is closed off with a stopper made from the wood, with one side cut off. At the place where the stopper ends, a whistle hole is cut into the bark, and one end of the hole is bent slightly inwards. Three to six finger holes are cut in the pipe. Wooden pipes are made of ash or linden wood. The bark is removed, and the instrument is hollowed out by burning, drilling or carving. The blowing hole, whistle hole and finger holes are made in the same way as for the
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
