Just designed and tested an algorithm to build a reverse-iterator on top of an iterator that can only run in forwards direction (part of the #musl collation project) and it seems to be good!
63 underlying forward-iterate steps to perform 21 reverse-iterate steps in simple test case.
if i'm not mistaken, the stack levels to maintain per index are invariant if one follows a strict log2 distribution;
e.g. the stack for #121 is { #64, #96, #112, #120, #121 } (since 121 = 0b1111001, so 64, 64+32, 64+32+16, 64+32+16+8, skip, skip, 64+32+16+8+1)
but it might be necessary to keep the growing loglevels to the MSB also; so, for our example, the stack starts with #1, #2, #4, #8, #16, #32 before reaching its peak at #64.
Never forget: "The Tiananmen Square protests, known within China as the June Fourth Incident, were student-led demonstrations held in Tiananmen Square in Beijing, China, lasting from 15 April to 4 June 1989. After weeks of unsuccessful attempts between the demonstrators and the Chinese government to find a peaceful resolution, the Chinese government deployed troops... in what is referred to as the #Tiananmen Square massacre." #1989#64#China https://en.wikipedia.org/wiki/1989_Tiananmen_Square_protests_and_massacre
Władze nie wierzy, że Chińczycy nie pamiętają, dlatego woli zejść z oczu. Xi Jinping nie pokazywał się publicznie przez dwa tygodnie i dzisiaj przyjął Łukaszenkę, ale nie w Wielkiej Hali Ludowej przy placu Tiananmen, ale w Zhongnanhai, zamkniętej rządowej dzielnicy.

What old movies hold up because of a lack of special effects or because clever use of effects?
What older movies made a good use of either side stepping special effects or have effects that somehow still hold up today? Why are they good movies?
