License check

We seem to be following the license from the original site, (although I couldn't find the problem number to add a link).

I've found the problem number which is 686. --PureFox (talk) 23:21, 15 January 2020 (UTC)

I was just about to add the (home page) information. I had originally phrased the problem much differently, but then it seemed to be more confusing and somewhat unclear, so I went with the original wording and phrasing that someone had paraphrased. I tried to find the problem on that website, but I couldn't find (I must have mis-remembered some keyword/keywords because I couldn't locate it via my search engine, other than it was on that site. -- Gerard Schildberger (talk) 23:29, 15 January 2020 (UTC)

Your RC title gives more info 👍 --Paddy3118 (talk) 12:25, 16 January 2020 (UTC)

significance of a given p value

I wonder what the significance is of saying that: "You are also given that p(123,45)=12710."? It's not as if it's going to take a long time to calculate whatever method is used. --PureFox (talk) 23:49, 15 January 2020 (UTC)

The reasoning behind that (I believe) was to give the programmer an answer so that it could be used for verification of their programming solution to check if their calculation was working correctly for a "modest" (or easy) expression/formula. -- Gerard Schildberger (talk) 00:07, 16 January 2020 (UTC)

Yeah, makes sense I guess. I'd been looking for a deeper meaning but couldn't think of any. --PureFox (talk) 00:12, 16 January 2020 (UTC)

is there an easy way to get those delta 2^i (delta = i-Last_i ) ?

searching for '123' there is a double 485 Delta

searching for '317' ( not the smallest at start, 1651 seldom )
