Talk:Successive prime differences
Different results for 6,4,2
I am getting slightly different results for the last group than the Python example and am finding it hard to see where I may be wrong. I am finding 337 groups. Am I just mising something? --Thundergnat (talk) 01:20, 27 April 2019 (UTC)
Doh! It's me, I glossed over the 'successive' part of the problem. Update to follow. --Thundergnat (talk) 01:25, 27 April 2019 (UTC)
Task background
It's my birthday soon so I googled my age and found:
- It's a prime.
- It's a twin prime.
I searched Rosetta Code and found that there was no twin prime task! (I had expected that someone would have already started it). I resolved to wait untill closer to my birthday then put up a twin primes task and left it at that.
A few days later I started to think of what a generalisation around the idea of twin primes would be and hit on a difference; then multiple differences; then really liked how my solution to generating a sliding group of <count> items from a list actually did come from the Python fundamentals:
- <lang python>zip(*(lst[n:] for n in range(count)))</lang>
I finished the code and played with the differences then firmed up what the task details would become. I wrote the task and added extra explanations and emphasis to try and help the reader grasp the details, then went to bed.
Today I've just done a search of the primes generated from differences of 2, 4
on OEIS to find that it is known to some degree, but expressed differently and not as generally as here - I guess recreational maths peeps think alike :-)
