[VA] Short & Sweet Math Challenge #25 "San Valentin's Special: Weird Math"

[EdS2]

Very nice, thanks again for the motivations and explanations.

Just one query: I'd interested to know the runtimes of some of these 71B programs. (Even if approximate, from memory.) For example, the time to find PP#1 and then PP#2. Another example, the most expensive calculation relating to the PP challenge - how long did that run for?

(If I had a 71B I could find this out directly!)

(Edit: answered in PM. VA (re)noting the use of go71b, about 128x faster than 71b, and taking 186s and 337s for PP's 1 and 2, and 4117s for PP# 1846. Noting also that a real 71b is about 10x or more the speed of a 41C. HP85 about 5x faster than 71. And noting that none of the code is written for speed.)
